Addressing the usual few complaints folks always bring up:
* This is from the separate independent team that works on Thunderbird, not Firefox, so there isn't any resource contention happening there
* Thunderbird is revenue positive, and this potentially gives that team another revenue stream to be even more self-sustaining through charging companies
* Businesses definitely want to control the AI they're using (especially with RAGs of their own data) instead of just throwing it at their LLM vendor and hoping for the best
People on HN are fond of asserting that their own POV is the only one. Imagine that there is such a thing as a person in charge of choosing technologies for organizations, and that you're such a person. That's who this is for.

It's a crazy crowded space. Any entry into this field looks like a "me too" product driven by FOMO instead of being motivated by (a) serving customer needs, (b) serving social needs, or (c) making money. (All of which are fine with me) It will get 0.5% market share -- and I'm supposed to get excited?
If you lived in New York City you might think there are Duane Reades coast-to-coast but there are not. If you are based in the Bay Area you see billboards that are very different from anywhere else. I'd say the viewpoint is a lot like this famous artwork
but maybe instead of the rest of the US being 1/5 of the vertical space it is 1/25 of the vertical space. Problem is most customers do not live in the bay area and most web browser users do not live in the bay area and most web developers do not live in the bay area. Based in the Bay Area they can hop in their cars and drive the longest 40 miles in America to get to Google and Facebook's headquarters so Mozilla is talking to those people all the time and not talking to the rest of us.
We don't get costly signalling to show they care about the rest of us, we don't even get cheap talk.
They probably think René Girard is deep because they are surrounded by people who think René Girard is deep. If Mozilla wants to be relevant and not just an also-ran it needs to "think different" like the other 99.9% -- it's not that hard if you change your location.
Really the EU needs to apologize for those damned cookie popups and invest in a privacy-first browser. Whether that is "fully fund Firefox" or "fully a fund a Firefox fork" or pick up another browser engine or start a new one.
I see the warning lights flashing: a few years back web sites that didn't work with Firefox were few and far between, this weekend I bought tickets for a comic book convention and they took my money but didn't give me a ticket because the site didn't work with Firefox. I use Firefox as my daily driver so all the projects that I work on work with Firefox; the rest of my team doesn't give a damn and if you lose me another site will become Chrome-only.

Thunderbird currently runs entirely on donations, even though they have paid products in the pipeline.
I think a piece of software running on donations is not running off "charity". It's just a business model to not charge every user. Similar to how Twitch streamers operate, or my local theater group.
Thanks, that's helpful. This says about ~70% of the money was paid to employees, ~10% infra costs, the other ~20% various other fees and smaller expenses.

For anyone reading this that has worked on the launch of this new product (or the many others of their ilk throughout the years) under the various Mozilla orgs, I mean no disrespect, however I feel it's important to not mince words these days..
I implore ANYONE at Mozilla org to please, please stop working on projects distracting from the complex and necessary work of browser and web standards stewardship. That alone should be the very reason for your continued existence if you have any. Focus on anything outside that purview will lead to the furthering of the, already painful and readily apparent, stagnation of your browser and our standards bodies as entities distinct from corporations.
Ditching any direct financial ties to Google or any other browser vendor is both important and necessary at this point, as this clearly represents a conflict of interest in your overall mission.
The web as a platform should belong to us all, not just the few corporate leaders of the day. I've watched in real time, saddened by the persistent errosion of our commons that is the web. I see it becoming nothing more than a corporate playground should trends continue, if it's not already too late. There may have been a time when your mission took precident over product launches of seemingly unrelated domains, but that is not what Ii observing today.
I think I speak for many in the community in these regards (please correct me if not the case.)

I am not trying to defend the projects they have chosen to work on, but you have to understand that reducing dependence on Google is exactly why they are working on them [1].
[0] Even when they did that, it was for the US only, and Google was still the default for most of the world.
[1] Although in this case, this appears to come from the Thunderbird organization, so unrelated to the browser. Money is fungible, though.

Right. Firefox stands alone as the most successful self financed full stack browser that's ever been made without being subsidized by outside revenue streams. I like to use the example of Opera. If "make a better browser" won market share and business creativity won stable revenue, we'd all be using Opera right now because (sorry Mozilla), no browser company was ever better than Opera in my opinion.
In 2026 the rules to making a good browser are (1) already be a trillion dollar company, (2) use Chromium, (3) have some form of distribution lock-in over billions of devices. Otherwise you're cooked. Mozilla swims against the stream better than anyone.

Imagine if MSFT was the sole contributor to Linux and how that would have shaped its development. In recent years MSFT may infact directly contribute developers and funding to linux, but they have a vested interest in doing so, as they run more Linux VMs in Azure than Windows VMs these days...

Because Windows doesn't go open-source and others can't build their OS from windows like chromium. With OS, there are no open source kernels that are actively maintained and security-fix bump every month by full time staff of giant corporation. With browsers, devs already have an open source engine with most of the work and build are from full-time staff of a giant corporation, and then they just lazily build "their own" browsers upon that and brag on social media.
Build your own browser engine and see how you can pay the devs to make them work on it.

In contrast, the Multi-Account Containers system is the primary reason I avoid Firefox.
While it is meant to be an alternative to Chrome's profile switching, it is more a workaround than a complete replacement. I need entirely different sets of extensions for personal, work, and school environments, something containers can't do.
Firefox's actual profile support is beyond terrible. To launch a separate instance, Firefox requires many more clicks than Chrome, all within a Windows-2000-style UI. Not to mention that there are weird glitches in their implementation.
Firefox is not usable for me until they actually spend time improving their multiple profile support.

Myself the profile support is the absolute worst thing about Chrome. I just want to log into some web site, I don't want to fight with the profiles to get things done.
For those few applications where I really would need profiles I will just open a different browser, so I still keep Edge/Chrome/Opera around for that rare situation. I don't need something that complicates my life every single click but it is the whole ideology of the Google Economy that they want you to spend 1% of attention on things that matter to you and 99% on things that don't.

Here are a couple:
1. The inability to set a specific page for new tabs to open on. That is ridiculous.
2. The mobile version sucks, specifically because bookmarks are buried under an absurd number of menu levels. And they're also broken up (without user approval or any way to stop it) into "mobile" and "desktop" bookmarks. WHY? The entire point of syncing is to have them all the same.
I want to like Firefox. I went back to Firefox for the first time in decades last year and gave it up after a couple months because #2 was that annoying. So brain-dead.
Oh yeah, and another one was that "never remember history" does, in fact, remember history. What Firefox really does is "stop adding to history." And the bug report on it resulted in several YEARS of debate over how to "fix" it. The latest I saw is that they're actually NOT going to fix it, but rather add more text (somewhere) to say basically, "This doesn't do what you think it's going to do."
If fixing a defect like that requires years of committee back-and-forth, the product is finished.

Web usb and serial are not just missing, last I checked Mozilla is opting to not implement based on their moral stance. It just puts them behind for some stuff.
It is so frustrating how every thread about Mozilla has people getting upset about contradictory things.
Half the thread impunes Mozilla for taking so much money from Google and imply that they are controlled opposition, and the other half gets upset when Mozilla doesn't implement every standard that Google tries to steamroll through the standards bodies because of objections to how they can be used for fingerprinting, or complains that the attempts at anti-fingerprinting break websites, etc.
Sometimes it's not even different people, it's the same people punching them for contradictory reasons.
Mozilla is not perfect but they get all the downsides of being methodical and privacy focused alongside none of the benefits. Everybody hates the "side projects" unless it's Rust, Servo, LetsEncrypt, Thunderbird, contributions to Opus/AVI, etc. and you can be sure they'll be criticized if they "focus" by touching investment in any of those by the same people.

Essentially all of Firefox' incompatibilities with a website reduce to Firefox not allowing the users to be tracked or fingerprinted by default. Webapps that rely on fingerprinting as a replacement for device tokens will likely not work. Because fingerprinting is bad and I don't want it to work. The people your bank pays to implement that are the same companies used for cross site tracking. It only works because tracking works. ReCaptcha can break for similar reasons, but there are better options for captcha and the need for captcha itself is possible to eliminate with various strategies depending on what it is being used to mitigate.

That's how they can block youtube ads, and no they don't code their own filters for youtube ads either. And be assure that they can't check 100% all commits from uBO and other lists either.
If you want to play "no trust to a 3rd party dev", you should not use Brave's adblocker either. Or at least turn off all the lists inside it, and use your own lists. Your security risk is in those stock lists.

I'm building a fairly complicated browser extension [0].
Debugging the extension on Chrome, it works great. On Firefox, it is nearly impossible. There are a litany of compatibility issues that make it "different" than Chrome, despite the extension being very much standards based. It is really frustrating and makes me dread getting bug reports.
To be fair, Safari is even worse and I haven't even touched Edge yet.
As much as I'd love to have options in the marketplace, standards based compatibility between offerings should be a top line requirement.
The standards used to be there. Chrome decided they made ad blocking too easy and unilaterally changed the standard. Firefox is still on the standard. Chrome is what deviated, and while performance was improved, that was definitely not the motive.

Upvotes are not going to make problems actually relevant to solve.
The question keeps getting asked because people say they have problems. Answers (if any come) tells everyone what the problem is for this one user that raised it.
In aggregate we can all see that the problems are not very real for the vast majority of users.
The biggest problem users actually face with using Firefox is that web devs don’t want to support more than one browser and they have picked Chrome now. Or IT departments have blessed one and only one browser on corporate machines and it is the one most corpoware developers build extensions for.
Chasing web standards is a second order problem and will not make the user experience better in a relevant manner for end users. If web developers want an open web, they have to work to support open browsers.
Yeah the criticism is not invalid, but it is also often half-relevant soapboxing and I would wager that is why it tends to get downvoted.

This "Mozilla is distracted" narrative is a category 5 hurricane of unsubstantiated vibes from people who have no idea what they're talking about.
Some quick hits just from reading recent release announcements from December '25 through April 26:
- Hardware acceleration for faster performance with PDFs
- Expanded WebGPU support
- Faster page loading with compression dictionaries
- Deeper hardware integration for faster video playback on AMD hardware
- Better GPU stability and performance on MacOS
- Faster local translation
And I'm only picking out bits and pieces. "Web platform" improvements are so abundant that reproducing them from any single release would be a massive wall of text, but for a few examples just from one recent release:
>Service worker support for WebGPU has been added, making it available in all worker contexts. Service workers allow WebGPU to run in the background, which is particularly useful for extensions and other pages that can meaningfully share resources across multiple tabs and time periods.
>Firefox now supports the Iterator.zip() and Iterator.zipKeyed() methods from the joint iteration proposal. This allows zipping together underlying iterators into an iterator over values grouped by position, similar to zip in many other languages.
>Firefox now supports the Trusted Types API, which is primarily aimed at preventing cross-site scripting attacks.
>Firefox now supports the Sanitizer API, which provides new methods for HTML manipulation. The element.setHTML() method enables developers to insert HTML content similarly to element.innerHTML, but without the security vulnerabilities such as cross-site scripting (XSS). A complementary method, document.parseHTML(), is also available for parsing HTML safely.
And on and on it goes with APIs, CSS and so on, and that's every release, and that's still not covering feature requests and cosmetic updates, or the constant security updates.
Guys, this is millions of lines of code and thousands of patches every quarter. While you were reading about AI features or poorly worded terms of service, they studied the blade..er.. they worked on real performance improvements. It should be a scandal that anyone in the comment section gets away with claiming they're not working on anything.

Mozilla is doing exactly what you’re describing. They need revenue to ditch their direct financial ties to Google (and I wonder if they hire those high-salary executives solely in the hope of generating that revenue).
These AI products, along with all previous failed attempts, are just them trying to gain enough revenue to remove that dependency on Google.

The Mozilla employees are just Google plants.

It has been my daily driver off and on again across the years since the Netscape code was open sourced and Mozilla as an organization was founded. It's a fantastic browser, but Chrome now owns the lionshare of the market as Firefox plays catch-up instead of leading like it did in the past. Memory isolation, etc never got the resourcing it needed to complete until it was apparently too late.
I see Firefox now as the new Opera, a technically good browser making dubious extensions that no one asked for until it dies a slow, spiraling death. My plea is simply to not go down that road any further...

I can understand where you're coming from, but this seems a little misguided. Are you personally trying to pledge at least 1 full devs salary to Mozilla in exchange for less AI products? At the end of the day this really comes down to the money. If you want Mozilla to do the things you say you want from them, they need more than donations. Good will doesn't build a browser, that shit's expensive. It's like you're asking for a games studio to just give you an MMO out of the goodness of their heart for a few scraps from people who support their mission. The world doesn't work that way, without products like these I imagine Mozilla wouldn't be around much longer in the way you describe considering most of their salaries are paid directly by that 'poison' you describe.

And I want those governments to commit to progressive enhancement guidelines like https://www.gov.uk/service-manual/technology/using-progressi... so new alternatives like Ladybird can start, and further require their agencies to test on a Firefox branch with no AI, no location tracking, full ad-blocking, etc. because while the market is free to ignore certain non-profitable users, a government should not be allowed to ignore some of its citizens.

Mozilla needs money to support the development of Firefox (and the payroll of its high-salary executives).
For now, they mainly rely on Google for that money. Google pays them to avoid antitrust cases, to show the courts that they are not a monopoly and that "alternatives" exist. For example, the DOJ once proposed that Google be forced to sell off Chrome.
However, if another entity has control over your budget, they also have control over your product. If Firefox becomes "too good" to be a true competitor in the consumer space, the funding might be reduced or even cut off.
Creating a new source of revenue allows Mozilla to improve Firefox even beyond the point Google feels "comfortable" with.

The anti-trust lawsuits with Google have Mozilla realizing they can't just be a company kept afloat by Google. Mozilla's priorities have been pretty complacent, basically just maintaining Firefox, sometimes Thunderbird, and a couple side services that have little financial incentives.

What even is this? A chat frontend to arbitrary model providers on the backend - I guess that's sort of useful not to have to build yourself but it doesn't feel like the amazing thing they're trying to hype. Some of the features seem a bit weird to me too - like end-to-end encryption? There isn't a server intermediary, so you already have that with TLS to the model provider.

Yeah it seems similar to Gemini Enterprise. There you can deploy "apps" (basically front-ends) on top of the LLM that come pre-configured with plugins to access Google sheets, Databases, your Jira boards, etc.
So all this is doing is adding context for the LLM and some persistence.
I have yet to see a compelling use case for Gemini Enterprise at my company but we're still experimenting with it.

Watefox, Librewolf have both plucked out all unnecessary stuff Mozilla added over the years. Both are good but Librewolf comes with history and cache disabled by default which may be bit surprising.
Floorp comes with additional custom interface features, workspaces (tabs grouping) and mouse gestures. And bit better profiles feature - Mozilla decided to redo it recently which lead to some problems.
Mullvad has build in VPN, DoH and proxy as an extension, and comes with uBo and NoScript.
There's Zen browser that has a quite uncommon UI, and obscure Pale Moon that IIRC still tries to provide old XUL/XPCOM extensions - which often leads to pages rendering issues.

A tip for Librewolf: you can easily toggle permanent cookie storage for a site through the "Always store cookies/data for this site" option in the shield button menu on the URL bar. This is very convenient compared to vanilla Firefox where you have to add exceptions through the settings.

Doesn’t this have to be done under another name to prevent massive company-killing pushback?
* This is from the separate independent team that works on Thunderbird, not Firefox, so there isn't any resource contention happening there
* Thunderbird is revenue positive, and this potentially gives that team another revenue stream to be even more self-sustaining through charging companies
* Businesses definitely want to control the AI they're using (especially with RAGs of their own data) instead of just throwing it at their LLM vendor and hoping for the best
People on HN are fond of asserting that their own POV is the only one. Imagine that there is such a thing as a person in charge of choosing technologies for organizations, and that you're such a person. That's who this is for.
If you lived in New York City you might think there are Duane Reades coast-to-coast but there are not. If you are based in the Bay Area you see billboards that are very different from anywhere else. I'd say the viewpoint is a lot like this famous artwork
https://en.wikipedia.org/wiki/View_of_the_World_from_9th_Ave...
but maybe instead of the rest of the US being 1/5 of the vertical space it is 1/25 of the vertical space. Problem is most customers do not live in the bay area and most web browser users do not live in the bay area and most web developers do not live in the bay area. Based in the Bay Area they can hop in their cars and drive the longest 40 miles in America to get to Google and Facebook's headquarters so Mozilla is talking to those people all the time and not talking to the rest of us.
We don't get costly signalling to show they care about the rest of us, we don't even get cheap talk.
They probably think René Girard is deep because they are surrounded by people who think René Girard is deep. If Mozilla wants to be relevant and not just an also-ran it needs to "think different" like the other 99.9% -- it's not that hard if you change your location.
Really the EU needs to apologize for those damned cookie popups and invest in a privacy-first browser. Whether that is "fully fund Firefox" or "fully a fund a Firefox fork" or pick up another browser engine or start a new one.
I see the warning lights flashing: a few years back web sites that didn't work with Firefox were few and far between, this weekend I bought tickets for a comic book convention and they took my money but didn't give me a ticket because the site didn't work with Firefox. I use Firefox as my daily driver so all the projects that I work on work with Firefox; the rest of my team doesn't give a damn and if you lose me another site will become Chrome-only.
I love them. They are not mandatory, only shady websites that rather sell users information than providing a barely functional homepage. Yes the popups suck, but I'm very happy that this exposes the behavior and priorities of the industry.
Yes, agreed on that. I'm not sure I'm clear how this really helps that; I suppose it's a frontend that they don't have, but there are a bunch of those already.
It doesn't seem to help them control the _actual_ AI, i.e. the model, which still has to come from somewhere.
https://www.thunderbolt.io/announcing-thunderbolt
I would rather have them work on Thunderbird.
(edit - to allow users to fund Firefox, allowing us to better sleep at night, and to align our incentives)
> Thunderbolt is funded through a dedicated investment from Mozilla and is being developed by a separate team focused on enterprise AI products, distinct from Thunderbird’s donation-supported consumer product work.
Surely you can agree that when you open Thunderbird and are met with requests for donations, if you chose to donate, you'd expect that money to be invested in Thunderbird development, and not 10M Claude tokens to vibe code Mozilla's latest groundbreaking AI B2B SaaS idea?
Hmm, I thought the for-profit Thunderbird pro hadn't launched yet?
I know Thunderbird is for profit, but what are they profitting from without the paid service, and how much of that profit is going into this unrelated Thunderbolt AI platform, exactly?
I think a piece of software running on donations is not running off "charity". It's just a business model to not charge every user. Similar to how Twitch streamers operate, or my local theater group.
You can read how they spent money in 2024 [1].
[1] https://blog.thunderbird.net/2025/10/state-of-the-bird-2024-...
It would be interesting to have a breakdown of what part of the Thunderbird team is working on Thunderbird, Thunderbolt, or other forms of thunder.
It doesn’t mean profitable, it doesn’t mean cash flow positive.
Are you just trying to say their revenue is greater than zero?
Is that why I'm met with a splash screen asking me to donate every time I start Thunderbird? Is this another Wikipedia situation?
[1] https://github.com/thunderbird/thunderbolt
As for Thunderbird, it’s not the same name? Idk what to say
I suppose there is no Thunderbird for Macs then? Or someone in the team would have noticed.
Then again, it's frustrating trying to name a product in today's era; too many names are taken.
I implore ANYONE at Mozilla org to please, please stop working on projects distracting from the complex and necessary work of browser and web standards stewardship. That alone should be the very reason for your continued existence if you have any. Focus on anything outside that purview will lead to the furthering of the, already painful and readily apparent, stagnation of your browser and our standards bodies as entities distinct from corporations.
Ditching any direct financial ties to Google or any other browser vendor is both important and necessary at this point, as this clearly represents a conflict of interest in your overall mission.
The web as a platform should belong to us all, not just the few corporate leaders of the day. I've watched in real time, saddened by the persistent errosion of our commons that is the web. I see it becoming nothing more than a corporate playground should trends continue, if it's not already too late. There may have been a time when your mission took precident over product launches of seemingly unrelated domains, but that is not what Ii observing today.
I think I speak for many in the community in these regards (please correct me if not the case.)
> ... please stop working on projects distracting from the complex and necessary work of browser and web standards stewardship.
> Ditching any direct financial ties to Google or any other browser vendor is both important and necessary...
are inherently contradictory. If you do not want Mozilla to have revenue from search vendors that also have browsers, it has to come from somewhere else. Or are you suggesting they switch the default search engine back to Yahoo [0]?
I am not trying to defend the projects they have chosen to work on, but you have to understand that reducing dependence on Google is exactly why they are working on them [1].
[0] Even when they did that, it was for the US only, and Google was still the default for most of the world.
[1] Although in this case, this appears to come from the Thunderbird organization, so unrelated to the browser. Money is fungible, though.
In 2026 the rules to making a good browser are (1) already be a trillion dollar company, (2) use Chromium, (3) have some form of distribution lock-in over billions of devices. Otherwise you're cooked. Mozilla swims against the stream better than anyone.
Take look at Ladybird
https://en.wikipedia.org/wiki/Ladybird_(web_browser)?wprov=s...
Besides, the one thing Mozilla could do to be relevant to 99.9% of web users is to move somewhere other San Francisco and turn their office their into a homeless shelter. They should go to Dublin or Frankfurt or Barcelona, anywhere.
Build your own browser engine and see how you can pay the devs to make them work on it.
Blocks ads Multi account containers Dev tools very good
I never notice that it is in any way slow, except for those sites that need infinity cpu on any browser, like jira.
What specifically is the issue? To my mind it quietly just gets on with things.
The Mozilla org continues to produce a very capable browser, but it's now 3rd or fourth fiddle on a stage their misteps helped orchestrate in their demotion.
Edit: clarification
Firefox is a little slow for an internal application we have that loads 40,000 rows of data into a grid but otherwise all our stuff works with it because I develop Firefox first and I think a few of us are all that really stands between Firefox and oblivion and probably are doing more work than a lot of the people they have on the payroll.
If you have specific sites that aren't working, please let us know and we can investigate and try to fix them.
The usual reporting channels are using https://webcompat.com or the "Report Broken Site" tool in the Firefox menu. Of course I"m also happy to take bug reports here if you (or anyone else) have them.
While it is meant to be an alternative to Chrome's profile switching, it is more a workaround than a complete replacement. I need entirely different sets of extensions for personal, work, and school environments, something containers can't do.
Firefox's actual profile support is beyond terrible. To launch a separate instance, Firefox requires many more clicks than Chrome, all within a Windows-2000-style UI. Not to mention that there are weird glitches in their implementation.
Firefox is not usable for me until they actually spend time improving their multiple profile support.
https://support.mozilla.org/en-US/kb/profile-management
None of those have required me to install a particular extension..
Of course thats not to deny your experience!
The only time profiles ever come into it, for me, is using web driver, playwright, or whatever.
I guess maybe the usage stats dont support making the profile selector better.
But also, maybe its a thing they would accept a change for?
For those few applications where I really would need profiles I will just open a different browser, so I still keep Edge/Chrome/Opera around for that rare situation. I don't need something that complicates my life every single click but it is the whole ideology of the Google Economy that they want you to spend 1% of attention on things that matter to you and 99% on things that don't.
As you yourself mention, Firefox has actual profile support, which may not be as good as Chrome's, but at least compare like for like.
And Firefox now needs 2 click to switch profiles.
1. The inability to set a specific page for new tabs to open on. That is ridiculous.
2. The mobile version sucks, specifically because bookmarks are buried under an absurd number of menu levels. And they're also broken up (without user approval or any way to stop it) into "mobile" and "desktop" bookmarks. WHY? The entire point of syncing is to have them all the same.
I want to like Firefox. I went back to Firefox for the first time in decades last year and gave it up after a couple months because #2 was that annoying. So brain-dead.
Oh yeah, and another one was that "never remember history" does, in fact, remember history. What Firefox really does is "stop adding to history." And the bug report on it resulted in several YEARS of debate over how to "fix" it. The latest I saw is that they're actually NOT going to fix it, but rather add more text (somewhere) to say basically, "This doesn't do what you think it's going to do."
If fixing a defect like that requires years of committee back-and-forth, the product is finished.
I've been using the "New Tab Override" extension for almost a decade at this point. Sure, it would probably make sense to have as a baseline feature, but I installed it so long ago and it's continued working the whole time that it's not really something I think about anymore.
What's wrong with Firefox? There are several things Firefox does that it's annoying to live without in other browsers (video pop-outs, competent ad blocking, etc). Is there some core feature that's missing? I'm subjected to Edge at work and I couldn't tell you a single thing it does that I'd want FF to do.
> and our standards bodies as entities distinct from corporations
Ok, I buy that.
Half the thread impunes Mozilla for taking so much money from Google and imply that they are controlled opposition, and the other half gets upset when Mozilla doesn't implement every standard that Google tries to steamroll through the standards bodies because of objections to how they can be used for fingerprinting, or complains that the attempts at anti-fingerprinting break websites, etc.
Sometimes it's not even different people, it's the same people punching them for contradictory reasons.
Mozilla is not perfect but they get all the downsides of being methodical and privacy focused alongside none of the benefits. Everybody hates the "side projects" unless it's Rust, Servo, LetsEncrypt, Thunderbird, contributions to Opus/AVI, etc. and you can be sure they'll be criticized if they "focus" by touching investment in any of those by the same people.
Yeah, double standards at its max. Firefox inputs every privacy concerns for these APIs that Google puts 0 Vietnam Dong to care about users' privacy. And those people cry about why Firefox doesn't implement it.
Yeah, it really undermines their ability to compromise user security and privacy.
I used something similar in the past. It was a legitimate use case for web usb which changed my mind on it quite a bit.
https://www.charachorder.com/ sells ergo keyboards and allows you to update their firmware directly in the website, through web usb. No local apps at all. Also an improvement in overall security from having to download some .exe / .dmg and running it locally.
Somebody also recently shared an awesome project which let's you use an usb printer regardless of your OS driver.
- PWA support on Linux
- better performance
- devtools should be able to handle sites with large amounts of js with sourcemaps
- fix a number of bugs that have been open for a long time
- don't lag behind standards as much (I'm not talking about things where they intentionally don't implement problematic "standards" pushed by google)
- make it feasible to embed gecko in other projects similar to how chromium is used by electron and webkit is used in "webviews"
If you want to play "no trust to a 3rd party dev", you should not use Brave's adblocker either. Or at least turn off all the lists inside it, and use your own lists. Your security risk is in those stock lists.
See e.g.
https://www.reddit.com/r/firefox/comments/1ljns9o/freshly_re...
Debugging the extension on Chrome, it works great. On Firefox, it is nearly impossible. There are a litany of compatibility issues that make it "different" than Chrome, despite the extension being very much standards based. It is really frustrating and makes me dread getting bug reports.
To be fair, Safari is even worse and I haven't even touched Edge yet.
As much as I'd love to have options in the marketplace, standards based compatibility between offerings should be a top line requirement.

It seems like every thread talking about Firefox always has someone asking that question, so if you search back you should find plenty of reasons. Unfortunately, it’s been my observation that valid and polite criticisms always get downvoted. I don’t understand why. It’s not like downvotes are going to make the problems disappear.
Most of us would like Firefox to succeed, and it’s none of our faults that Mozilla is constantly neglecting it and going off on wild goose projects which get promptly abandoned.
The question keeps getting asked because people say they have problems. Answers (if any come) tells everyone what the problem is for this one user that raised it.
In aggregate we can all see that the problems are not very real for the vast majority of users.
The biggest problem users actually face with using Firefox is that web devs don’t want to support more than one browser and they have picked Chrome now. Or IT departments have blessed one and only one browser on corporate machines and it is the one most corpoware developers build extensions for.
Chasing web standards is a second order problem and will not make the user experience better in a relevant manner for end users. If web developers want an open web, they have to work to support open browsers.
Yeah the criticism is not invalid, but it is also often half-relevant soapboxing and I would wager that is why it tends to get downvoted.
As for HEVC, that particular licensing trash fire continues to burn bright. VVC had an opportunity to learn from the situation, and decided what they really wanted was a trash fire that burned even brighter.
So, we might be stuck with H264 for a little bit.
Some quick hits just from reading recent release announcements from December '25 through April 26:
- Hardware acceleration for faster performance with PDFs - Expanded WebGPU support - Faster page loading with compression dictionaries - Deeper hardware integration for faster video playback on AMD hardware - Better GPU stability and performance on MacOS - Faster local translation
And I'm only picking out bits and pieces. "Web platform" improvements are so abundant that reproducing them from any single release would be a massive wall of text, but for a few examples just from one recent release:
>Service worker support for WebGPU has been added, making it available in all worker contexts. Service workers allow WebGPU to run in the background, which is particularly useful for extensions and other pages that can meaningfully share resources across multiple tabs and time periods.
>Firefox now supports the Iterator.zip() and Iterator.zipKeyed() methods from the joint iteration proposal. This allows zipping together underlying iterators into an iterator over values grouped by position, similar to zip in many other languages.
>Firefox now supports the Trusted Types API, which is primarily aimed at preventing cross-site scripting attacks.
>Firefox now supports the Sanitizer API, which provides new methods for HTML manipulation. The element.setHTML() method enables developers to insert HTML content similarly to element.innerHTML, but without the security vulnerabilities such as cross-site scripting (XSS). A complementary method, document.parseHTML(), is also available for parsing HTML safely.
And on and on it goes with APIs, CSS and so on, and that's every release, and that's still not covering feature requests and cosmetic updates, or the constant security updates.
Guys, this is millions of lines of code and thousands of patches every quarter. While you were reading about AI features or poorly worded terms of service, they studied the blade..er.. they worked on real performance improvements. It should be a scandal that anyone in the comment section gets away with claiming they're not working on anything.
These AI products, along with all previous failed attempts, are just them trying to gain enough revenue to remove that dependency on Google.
Do you want people to pay to use Firefox?
https://github.com/thunderbird/thunderbolt/blob/main/docs/fa...
> Thunderbolt is funded through a grant from Mozilla.
Is there any way that that's not taking dollars out of the same organization that's funding Firefox or thunderbird?
I see Firefox now as the new Opera, a technically good browser making dubious extensions that no one asked for until it dies a slow, spiraling death. My plea is simply to not go down that road any further...
This reads like a kid trying to give business advice to an adult. “You could do THIS, then THIS, it would also be cool if you did THAT but please don’t do THAT!!”
C’mon now.
The fact that is being run like one, albeit poorly is exactly the problem.
I don't think you realize the irony in calling my post childish here. "C'mon" I guess?
The FAQs in Github also imply that a hosted deployment for single users is on their roadmap, but not prioritized. - https://github.com/thunderbird/thunderbolt/blob/main/docs/fa...
Also Thunderbolt is too similar to Thunderbird, really got me puzzled for a sec.
Investing on AI is not going to make them less financially reliant on Google.
I want them to go cap-in-hand to other countries and say "if you don't fund us then you are letting the US and surveillance capitalism get between your citizens and their government" and "do you really know what Chrome is doing with your data?"
I don't want to pretend they are simply part of a browser marketplace, but rather have them realize they are part of a civil rights effort, with powerful non-market forces they can ally with.
And I want those governments to commit to progressive enhancement guidelines like https://www.gov.uk/service-manual/technology/using-progressi... so new alternatives like Ladybird can start, and further require their agencies to test on a Firefox branch with no AI, no location tracking, full ad-blocking, etc. because while the market is free to ignore certain non-profitable users, a government should not be allowed to ignore some of its citizens.
I don't see a contradiction there.
It looks like they might want to get into hosting/selling services to users on this.
From the FAQ:
> Is there going to be a hosted version if I don't want to deploy it myself? > Yes, we are planning to launch Thunderbolt for regular users but we do not have a release date yet.
The world may need Firefox but it's funny how people complain about Mozilla's dependence on Google while also complaining about every attempt to become more financially independent from Google.
For now, they mainly rely on Google for that money. Google pays them to avoid antitrust cases, to show the courts that they are not a monopoly and that "alternatives" exist. For example, the DOJ once proposed that Google be forced to sell off Chrome.
However, if another entity has control over your budget, they also have control over your product. If Firefox becomes "too good" to be a true competitor in the consumer space, the funding might be reduced or even cut off.
Creating a new source of revenue allows Mozilla to improve Firefox even beyond the point Google feels "comfortable" with.
The current state of Mozilla is pretty odd since they rebranded to make it more apparent they're a non-profit, while also attempting to become more profitable pushing out new products and services.
https://gs.statcounter.com/os-market-share
I've already used up "cum" btw, so you're not allowed to name your product that.
At a glance it looks identical to Mozilla Thunderbird, but has nothing in common.
And then of course it's also the same as a well-known hardware interface.
I know it's hard to come up with names and pretty much everything is used by something else, but this seems particularly bad.
The cherry on top is that the domain is thunderbolt.IO. No other TLDs to pick from?
Fire-fox
Thunder-bird
River-wolf
Stone-raven
....
Also, my impression is: yay another AI front-end. What does this one differently that the other thirteen in a dozen don't?
Mozilla's a lot more trustworthy with privacy and data, and they're unlikely to sell the project to someone who only wants to stuff it full of malware/adware/crypto stuff - or do it themselves.
Nobody I'd mention on Hacker News!
If you were not working with Mozilla Asian area, you know far too less. They had a browser in China that redirect to different website for profit before every connection and some affiliation. By doing so, is it privacy or not? Oh, look at Mozilla Japan volunteers, they shut everything up because things went wrong.
They're certainly doing better than others in this space, but their track record does not inspire confidence for anyone concerned about their privacy and data.

Coming soon the browser rebrand to Thunderfox! :)
"I'm using Mozilla Thunderbolt."
"Huh, do you mean Thunderbird?"
"No, Thunderbolt!"
Why not "Phyrefox"?
They are so incompetent, they could not even come up with a name sufficiently different from their own product.
Okay, it took me some time that the mail client is called "ThunderBIRD", not the BOLT. Not that I've used it much. But why the logo in github still shows TunderBIRD?
It looks like Mozilla is trying to catch the band wagon for no particular reason. They don't need it AT ALL. But they just jumped in along for a ride.
