Firefox has a market share around 3%. Even most technologists stopped using it long ago. Many banks and government websites don’t even support it anymore and loudly tell people to use Chrome instead, especially in developing countries.
Nothing can kill Firefox, because it’s already dead for all practical purposes.
I use Firefox as my daily browser. If i have a website that fails to work, I might try chrome maybe once every two months. And then it usually also doesn't work. So for all browsing I do on the internet, Firefox works like a charm
Get the OneTab extension. It'll save and close all those tabs. That way you won't have Firefox crashing during startup once you exceed the number of tabs it can handle (a few thousand).
Tip: the crashing is caused by certain extensions such as OneTab and All Tabs Helper which for some reason seem to cause all the tabs to load, just when restoring a session. Temporarily disable these extensions before restoring, then you can reenable.
Reading comments here about problems using Firefox is odd to me as I never run into them. I feel like people are taking about totally different browsers. I don't remember the last time I had page rendering issues or was asked to use a different browser.
I've been using Linux on my desktop for ten years and I definitely experience bugs and performance issues with Firefox from time to time that don't occur in Chrome. It's rare but common enough to keep Chrome around as a fallback.
A few: Developer tools are quite slow; Airline websites often break during checkout; JS games and video players sometimes stutter or use a lot of CPU
My favorite anecdote on this front: someone posted a comment on Lemmy, a fediverse alternative to Reddit, claiming Arch was "broken" and Linux users were delusional for thinking it was functional for the average person.
And when people ask them what they meant, they revealed that they used some package from the arch user repository that apparently required manual compiling for every update.
And instead of thinking that this wasn't the unusual behavior of a particular package, they insisted that this was the normal Linux packaging experience, which was why Linux as a whole was a terrible operating system.
A bunch of commenters chimed in emphasizing that the whole package distribution system in Linux is designed to among other things, handle dependencies and avoid manual compiling (though it's available as an option), and they were all dismissed as just being fanboy apologists.
Same. I mean, I'm sure there have been cases where I've switched to Chrome for certain things. I just got a custom viewfinder for my partner for Christmas, is showing a bunch of photos of the cruise that we went on. And they have an online editor for it, but the editor seemed to be glitching when using Firefox. So I moved to Chrome. Later I realized I was just misunderstanding and it actually just worked fine in Firefox.
And I'm able to access my bank, my credit cards, my utility bills, in Firefox without issue. So I'm not sure what people are talking about.
One thing I am familiar with though in the aftermath of gamergate was a bunch of motivated reasoning to complain about games and insist that they had design flaws or bugs, when really? The bugs weren't real but were kind of just a different way of saying We Don't Like This Game. And so reports of perceived bugs in some cases are as much a social phenomenon as they are a sincere representation of software functionality.
I don't want to say there's no bugs but for every one person's unsubstantiated anecdote, I seem to be able to find two people able to reproduce a functional version of the experience without issue. And just to zoom in on the bank login issue in particular, I use a credit union with an old decrepit HTTP site that was recently updated to a slightly less old and decrepit HTTP site. Plaid is unable to successfully log in, but the web interface works perfectly fine on Firefox mobile.
Most of the service sites I use are fine in Firefox running on Linux. The only thing I use that is problematic is the Microsoft 365 with Teams portal an employer uses. So I have Chromium just for that one.
Yes, I wonder if the rise of the Web Platform Tests have made browser behaviour much more consistent?
It happens so rarely, I don’t keep Chrome installed and have to download a new version of Ungoogled Chromium when I need to see if something only works in Chrome, which I can only remember doing about twice in the last year!
It's not page rendering issues, usually, since Firefox and Chrome pretty much support all the same things.
What you run into the most is the website saying, hey, it looks like you are not using a browser we have tested against, so we are not going to let you log in. Please come back when you have Chrome, edge, or Safari.
That happens quite often these days. Last week I was filling in a govt form (EU country), submit button didn't work in FF, so I had to resort to using Microsoft Chrome. On my company's training platform videos aren't rendered in FF. Another shitty corporate portal which shows my salary and holidays doesn't work in FF at all, completely. What else... A few smaller payment providers weren't working in FF over past two years. Ghost of the Skype before being finally killed only worked in Chrome clones. Stadia only worked in Chrome (yes, I used it and it was fine).
Also many sites show significant degradation in FF lately. Youtube works like shit in FF, once every 10 page opens it just gets stuck half way with part of the background loaded, like black with black empty frames on top. Or just empty page. No, it never finishes loading from that state, and neither it can reload on F5. But opening a new tab works fine and YT loads normally.
And to finish off this rant, FF has now started corrupting my open tabs after opening FF with saved session. This never happened since this feature was implemented and in 2025 has happened 3 times already. And in mozilla bugtracker all tickets about this are ignored for years now. Meanwhile they are developing some crappy bells and whistles, instead of fixing fundamental bugs.
If not for Chrome monopoly, I would consider switching browsers. Ladybird can't come soon enough. Mozilla has lost touch with reality.
Having switched to Firefox about 10 months ago, one thing I notice is every site I visit works but a lot of sites load way slower than Chrome. YouTube is a big one.
How much of that is Firefox rendering being worse vs artificial slowdowns by Google owned sites kind of doesn't matter in the end. Objectively it's a slower browsing experience but I solely use it for uBlock Origin.
I've been using Orion browser (WebKit-based with support for Chrome and Firefox extensions) for quite some time and haven't had this issue with YouTube, but I've definitely experienced the same with Firefox. If it's an issue of artificial slowdowns, you'd think they'd apply it to anything not running on Chrome's engine, which makes me think it's specifically Firefox's rendering causing this issue.
For me the biggest offender are usually Google products and sometimes the lazy-coded website written by incompetents and whose audience is the tech illiterate (i.e. some websites involving schools/teaching) that just tell you "use latest Chrome just to be sure, download here" to, well, just be sure.
Notable mentions for government websites that are like 10 years in the past and that are still on the "Supports Firefox" side because, well, they are just always late to everything.
Usually that's because of third party cookies the government websites love to use for authentication. FF and Safari by default blocks them but both can be disabled temporarily to use those websites. Chrome is more lax on them since ad networks love cross origin cookies as well.
While governments battle big tech on some issues, they are very much on the same side on others. They both want more tracking for example - the governments want to regulate it, and there is a battle for control of the data, but both want the data to be collected by someone.
3% market share is 150 million active users give or take. That's no death by any count in the software world.
Gosh, I really wish Mozilla would just dig into their user-base and find a way to adequately become sustainable... or find a way to make it work better as a foundation that is NOT maintained by Google, ie like the Wiki Foundation. I do spend a LOT of time in FF, can't anyone see there's a value beyond selling ads and personal info that could make Mozilla more sustainable, dependable and resilient?
I think you're right, but it's important to emphasize many of these attempts to tell the story of market share get major facts catastrophically wrong. The decline in Firefox market share from like 33% to below 10% is mostly because the world pivoted to mobile, and Firefox "dominance" was in a world of desktop browsers. It was defaults and distribution lock-in as the world pivoted to mobile that led to the change in market share. As well as the web as a whole effectively tripling in number of users, and Google leveraging its search monopoly and pushing out Chromebooks effectively at cost.
For some reason that part of the story always seems to get omitted, which I find bizarre. But the web pivoted to mobile and Google flexed its monopoly powers. I would argue that upwards of 95% of the change in market share is explained by those two factors.
No, the decline of Firefox market share happened in the early 2010s, on desktop, when everyone switched to Chrome because it felt way faster. I say "everyone" - this is the subset of "everyone" who were switched on enough to use a non-default browser in the first place. The rest used IE or Safari, dependent on platform.
What happened in the last 6 months or so to affect those numbers? According to them, Chrome increased in percentage quite a but recently and the others all got "compressed" towards 0.
Looking at the last 10 years gives a different perspective (not great for Firefox but maybe underscores something is different recently in general):
I can't imagine browsing the web on my phone and tablet without Firefox mobile. That would honestly be the biggest loss once this CEO takes this nonsense to the logical end.
I'm genuinely curious. What does FireFox mobile have over it's competition?
You can't install UBlock Origin on mobile.
Like I still use FireFox on mobile, just purely out of habit. I don't really see anything better about it (I am quite inexperienced when it comes to phones).
Pretty sure even back then, uBO was on the list of vetted extensions. I remember using it prior to 2023 (since like 2019), on my old OnePlus 6. There may have been a period it wasn’t available, but surely it wasn’t gone for too long.
I use several extensions on Fennec mobile: AdGuard AdBlocker, Google & YouTube cookie consent popup blocking, NoScript, Privacy Badger, Translate this page, Web Archives, uBlacklist
> Many banks and government websites don’t even support it
Because their web developers are too lazy to write anything to proper standards. They're doing some kind of lazy "Check for Chrome, because everyone must be running that, if not, redirect to an Unsupported page".
I've yet to find a website that "refuses" to work in Firefox which doesn't work just fine when I use a user agent switching extension to present a standard Chrome on MacOS or Chrome on Windows useragent.
When they say "don't support it anymore", does that mean they're back to the IE era of using Chrome specific technologies so it doesn't work in any browser, do they use user-agent sniffing and show a big popup, or is it just that they're not testing it in FF anymore? The latter shouldn't be an issue as long as they use standards, the only thing they would run into in this day and age is browser specific bugs - but Safari seems to have that the most.
Have not used Chrome-based browsers 3+ years and never had problem with Firefox. Sometimes Safari was not working 100% - but nothing serious. Maybe it is because, only page from google I use is Youtube; however Firefox has best experience there, even better than Chrome - thanks to proper uBlock Origin.
Yeah, every website has different stats about user-agents, depends a lot on the types of users you attract. I bet HN has Firefox usage ratio above 15% for sure, while sites like Instagram probably has way below the global average.
Global browser marketshare never made much sense. You need to figure out what your users use, then aim to be compatible for most of those, and ignore any global stats.
As of December 7th, Firefox is 10.3% of traffic there. This makes it the #2 browser, after Chrome (at 62.2%) -- a spot it has been dueling with Edge over for the last year or so.
I'm inclined to think that "people visiting wikipedia" is a fairly representative sample of "normal users", overall.
Given the current state of the Chrome family of browsers and the anti adblocker stance from Google, i'd think that alone would guarantee Firefox a steady user base.
Not sure how users cope with Chrome-based browsers and intrusive ads.
That's just a wishful thinking. Too many ordinary users accept ads as inevitable annoyances and don't even know about the very existence of adblockers.
You could suggest installing Firefox next to Chrome and install uBlock Origin on it. Open YouTube and show them that there are zero ads. They will likely see a contrast.
I've tried a few times to convince people in my life who would self describe as "bad with computers" to download an adblocker, but they usually find the friction too high. Adding extensions is unfamiliar for most, and even if it seems very basic for us, the non-tech people I know don't really want to deal with the risk of unknown unknowns from that, let alone switching to a healthier browser. (Perhaps reasonable since it feels like these days half the extensions on the Chrome Web Store are spyware or adware behind the scenes.)
I also suspect that those who lived through the days of frequent Windows errors and Chrome running out of memory all the time often expect software to fail in weird and unexpected ways, and a lot of people adopt a "don't fix it if it isn't broken" mindset.
Still, uBlock Lite and Brave browser are definitely easy wins and I'm glad to see more random people in my life using them than I would have expected. :)
If it's the computer of an older family member or something, just put Firefox and ubo on their system for them and be done with it. They will use whatever software is preloaded, and being shown how to use it is a much lower barrier to entry than the cognitive load of finding, vetting, installing, and configuring new software.
I used to try to patiently explain why people should do xyz. Now I explain to people why I'm going to change xyz on their device, and if they don't slam the breaks I just do what needs to be done right then. If someone doesn't know what an adblocker is they are getting one so they can see for themselves and reflect on what companies have been putting them through for years to make some incremental amount of money.
That's really funny. Yes, in case it wasn't clear for others reading this and thinking about installing these, it's almost certain that uBlock Origin and Brave browser will not cause you any problems and if you're using stock Chrome I really encourage you improve your situation dramatically for ~5 minutes worth of effort.
that 3% is of total users including mobile which chrome is king because it's basically force fed to users. this is important because there is no choice with browsers for the common mobile user, most of them don't know what is a browser even if they used it every day.
also in the 2000s IE was king because guess what? that was what came preinstalled with winxp
Exactly! I keep banging this drum but I'm fascinated by the possibility of Android being required to have a pop-up where people can choose different browsers, as a potential remedy to Google's monopoly. Because engineering a path dependency on Google search, from mobile hardware, to software, to default browsers, to default search on the browser, I think is part of how they've enforced their monopoly. There's been a legal judgment that they are, in fact a monopoly, but I don't think any remedy has been decided on yet. And there's a lot of historical precedent for a pop-up to select a default as a remedy to software monopolies.
Granted in Google's case, it seems that the Monopoly judgment was with respect to ad markets, but locking people into search to serve ads might be understood as part of the structure of that monopoly.
Most of those sites are doing a little move called "lying". I occasionally (once every couple of months) run into a site claiming to not support Firefox. I can't recall a single site that wasn't a tech demo of some bleeding edge feature of Chrome that didn't magically start working when I turned on my Chrome UserAgent.
(Hey, if you work at Snapchat: fix your shit. Your desktop site is by far the most mainstream website I've come across that lies like this)
This is completely untrue in my experience. I use firfox exclusively on my personal laptop and have done exclusively for years. I don’t even have chromium installed.
I can’t remember the last time a website was unusable on firefox. It’s certainly not common.
My software stopped working because its drawing on canvas in a way that causes firefox to glitch with hw acceleration enabled. Not one of my customers/users complained
The only reasons I've ever put effort into Firefox support in my software was A) I find it helps push me to write towards standards better if I include multiple browser engines, which makes it more likely I'll support Safari without extra effort, which is difficult for me to test on because I don't daily drive any Apple devices (works about 80% of the time), and B) to avoid the shit-fit I would receive if I ever posted it as a "Show HN." It has never come up as an actual user requirement.
Nothing can kill Firefox, because it’s already dead for all practical purposes.
