Improve Adblock capabilities, better tab and session management, improve sync, improve site css and js management, built in dark-mode.
Hell, just look at the list of most used extensions, it’s a great place to start understanding what users want.
Who says they don't? They've pushed 23 new releases since 2025 with thousands of updates that include exactly the bug fixes, performance improvements and security fixes you're talking baout. This latest release, v157, includes the built in dark mode you're asking about (I just saw it on the popup on first launch when installing this new version) and the release notes describe improvements to tabs. v156 included huge performance improvements and they're regularly pushing tons of CSS updates across practically all of the releases.
I don't understand why people claim these things aren't happening when they're regularly documented on their release notes page.
It has built-in dark mode, check out the Themes in your settings.
Building a whole user interface to declare the setting of that preference per-site seems like a pretty high cost for something that won't be used by very many people. Most people just want the site to match their current preference. Instead, websites usually provide a way to override the setting which is stored as a cookie or whatever. I think overriding that value belongs in an extension, not as a core browser feature.

The whiplash from seeing that selectable on my screen to seeing someone claim it's not there in the same 60 seconds is really something.
Sadly, I think some of the heat is driven by culture war issues so people feel the need to pick a fight rather than simply ignoring something which doesn't suit their needs.
> OMFG! Look at the massive amount of space between the stupid pill shaped tabs ... If I wanted to use a shitty safari UI that sacrifices usability for cutesy looks, I would use Safari. ... Mozilla: why in the hell do I need to trust some extension builder to give me an amazing UI/UX?
and just a few top-level comments downthread:
> Are they forcing this? You have got to be kidding me. Why is this happening? Is this making them money or is this to cater to the ego of some product manager? ... What a fucking hostile, brazen change. Yeah, fuck you too Mozilla.
Something about Firefox makes people behave like absolute maniacs.
This will expose my internet user age but I remember Marcos Moulitsas talking about DailyKos redesigns, and he noted, correctly I think, that regardless of what you do, a visual redesign will be interpreted as an apocalyptic event to approximately 1/3 of the user base. But it tends to be a flame that burns bright but brief.
Or for another version: there was a time in the history of Facebook where redesigns to the desktop version caused user outrage and mass organization into aggressively titled Facebook groups, protesting for a change. Now I personally think that in many significant respects Zuckerberg is a fool, his investment in meta and VR has been a joke and his perspectives on AI are naive. But I actually think the design and iteration of Facebook itself has been a savvy series of careful iterations, and going this long without shooting himself in the foot is not something to be taken for granted.
Anyway, my point is as a going concern whenever you do a redesign you have to price in a certain amount of recreational outrage from a percentage of the user base that burns bright but brief.
That just means that, once it's been established that you're ignoring them, everybody who vocally hated the new design will switch to silent resentment of you for what you did, forever and ever.
No.
You're talking about a browser that has shed about 92% of its userbase since its peak. Firefox was never a default or a pushed selection, people were drawn to adopt it because they wanted it, and almost all of them were alienated and confused by the decisions that the browser made and continues to make.
In trying to make sense out of this own goal, they see the massive payments from google to firefox, they see firefox intervening in google's antitrust case, they see executives being paid an enormous amount of money for continuous failure, and they watch the slide continue. To see these and avoid understanding this as firefox taking a dive (that should be illegal, would be nice if we had antitrust) is a sort of blindness. It's also not to be blamed on some UI designer who just got there a few years ago - those red herring "real people" - these are corporate decisions.
If I invested with you, and you lost 92% of my money, there's no degree of heat that would be out of proportion.
> unbelievably hostile product space.
If you're subsidized a half-billion a year from your biggest competitor, and you started with a browser that was probably 35% of the market at peak, there is nothing hostile about this product space. It is the easiest job in the world. Especially if the job is to fail.
I don't think so. I've never been alienated by it. It's a browser. It does browser things. It's fine.
What decisions have confused and alienated you? People in this thread are screaming bloody murder because of a couple pixels on tab bar and a low-contrast gradient. This isn't a rational reaction to a minor graphical tweak, it's bonkers hysterics.
It turns out it's really tough to compete with one of the largest companies in the world when they are very highly motivated to capture as many users as they can (unlike Microsoft around the turn of the millennium). I think there are things Firefox could do to recapture the audience[1], but I also don't think turning the tabs into pills or whatever justifies the kind of language being used in this thread.

The inconvenient fact for these anti-Mozilla narratives is that most of those losses were in the 2010s before any of the side bets that people point to. The side bets era is approximately the 2020s, and the big market share losses were approximately in the 2010s, and so the side bets couldn't retroactively have caused the market share losses, and the actual market share losses of the 2020s are real but not consistent with the hysterical narratives that come out in the hn comment sections.
And the other inconvenient fact for these polemics is that actual driver of market share change is Google's dominant position as the world's most visited website and as a distributor that gets to pick the default browser on more than one billion Android devices and counting.
When Microsoft Edge grew it's market share, it wasn't because users A|B tested it against Firefox and found it more preferable, it's because it was a preinstalled default that gained ground over device churn. When Opera had practically the perfect browser in 2011-2012, they didn't conquer the world. When Mozilla did their massive quantum overhaul that delivered huge advances in performance and stability, their market share continued to decline. There are natural experiments left right and center testing the claim that market share is a perfect 1 for 1 response to changes in browser design, and so far they've failed to confirm that hypothesis.
Meanwhile the accusation seems to change on a nightly basis. Yesterday someone was outraged that anyone would dispute that average users don't care about any of this, they just want whatever browser is in front of them as long as it's fast and stable enough (so they claimed). Today, you've tagged in to claim users are hyperfocused on the minutia of Mozilla's design decisions on a day to day basis. Tomorrow somebody's going to claim it's really about something else. The only thing these competing explanations have in common besides hysterical exaggeration, is that they rely on unverified Trust Me Bro stories that never address the inconvenient fact that Google's distribution advantage is the primary driver of market share change. It feels like recreational outrage.
So they are practically speaking the only game in town (Brave being the exception on Chrome as they are keeping support for UBlock Origin)
Firefox Nightly on Android also allows desktop extensions to be used.
