Hello there. Unfortunately, according to Netflix help pages, Firefox Linux is limited to 720p, unlike Windows or macOS version. Opera is the only linux browser allowed to stream Netflix at 1080p.

This is a Netflix side limitation because using a fake user-agent is a workaround.

I have reported this problem to Netflix, it appears to be a DRM limitation. My report to Netflix have been share with their tech team, but I doubt that leads to anywhere.

Question : why this limitation ? Is the Widewine codec implemented differently in linux version ? Is there a way to make Netflix change their rules from Firefox team ?

I have Linux OS Mint Cinnammon 22.2 and firefox 145.0.2 I have ticked "Save and auto-fill payment info" and my credit card ## are recorded. When I want to pay, the default credit card ## appear correctly, but if I click on them to apply, nothing happens. Every time I have to re-enter all the numbers ! Many thanks for your answer.

I’m trying to install the latest version of Firefox on Debian, as described at https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions. I’ve tried twice, several days apart, but both times things fail at the third step, with the fingerprint not matching. Can I do anything besides try again later? I’m using Firefox ESR, as packaged by Debian, in the meantime.

Will this fricking "The bookmarks and history system will not be functional" B.S. ever be fixed? Firefox didn't have this issue for years now for almost a year every time Firefox starts up on a cold boot I get this idiotic non-sense message!. I have to close the browser I JUST OPENED and reopen in. This error is pure B.S. as again cold boot, just launched there is NOTHING other than Firefox that might be accessing the various sql.db's...so if this message is to be believed Firefox is blocking Firefox from Firefox... FIX THIS!

I've been using Firefox for years because more popular browsers like Chrome and Edge have anti-features I dislike. In recent years, however, it feels like Mozilla has been more eager to follow trends set up by it's larger competitors even when those trends seem destructive to the principles that used to be at the core of this project. AI is the final straw for me. I don't understand why I would even use Firefox over Chrome if both are full of AI anyways. Even if AI wasn't a deal-breaker for me, I'm worried Firefox will make similar decisions later. I want out.

Is there any good and maintained alternatives to Firefox? Something like how Firefox was just a handful of years ago? Maybe a fork of an old version?

Firefox in Ubuntu Linux is broken for about 30% of the web; only CHROME works. This problem just keeps getting worse. Please fix; it doesn't matter whether FF is more secure, if it doesn't work - what's the point?

I was positively surprised recently when the new Firefox profile manager (about:profilemanager) was introduced. https://www.tech2geek.net/how-to-use-the-new-updated-profile-manager-in-firefox-2025/ is an article about that.

However, I thought it's just a new visual UI with an in-browser switcher for the existing profiles (that I already had setup). However, it does not appear so.

The differences I see:

1. 1. 1. old profile management

• was managed by `about:profiles` or when starting FIrefox with `-P`
• is saved in `~/firefox` and the `profiles.ini` clearly and quite obviously mentions them there, so it's easy to manage them.

I also found this old support article: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

1. 1. 1. new profile management

• automatically asks on startup if more than one profile exists
• is managed by `about:profilemanager` or with the Firefox burger menu
• seems to be saved in `~/.mozilla/firefox/Profile Groups` (Linux path here) in some .sqlite files, and I do not quite understand the format. Not mentioned in `profiles.ini`.
• also, when you change something here (even like opening a profile?), you cannot open `about:profiles` anymore, because it says "Some Firefox process has made changes to your profile, […] you need to restart Firefox", only after a restart further changes would be possible, which I find quite confusing but it also indicates somehow the features belong together?

And this seems to be the new one: https://support.mozilla.org/en-US/kb/profile-management#w_whats-the-difference-between-profiles-and-multi-account-containers

1. 1. Questions

• What are the differences here (I may have missed)?
• How can the new profile feature save so few files? Is it technically called "profile groups"?
• And the most important: How can I migrate an old profile? (In order to use the new features and GUI etc. I quite like)

I just installed the browser and enabled Russian localization. Then I opened a page in English. A notification appeared with a suggestion to translate the page into another language. In the translator options, there is an option to select the language from which the translation will be made. There is Russian language there, but I chose English, it’s logical. And then comes the choice of the language into which the translation will be carried out, but there is no Russian language there. Why? How can I translate the page into Russian?

Hi Firefox community,

I’m not your usual tech influencer or a corporate “enthusiast”—I’m just a longtime open source user who’s spent more than a few years behind the veiled curtain, watching how this world of software and possibility unfolds. I love what Mozilla does for users like me. That’s exactly why I want to raise something: I keep seeing the word “chatbot” show up for Firefox’s new AI-powered assistants (like the sidebar and what’s coming next). But let’s be honest—“chatbot” belongs to the days of robotic customer service and scripted dead-ends.

What we have now in Firefox—powered by real LLMs (Large Language Models)—is a whole different species. Calling these assistants “chatbots” just doesn’t fit. It sells short what LLM-based assistants can do: they’re powerful, context-aware, and, at times, strikingly human in their conversation. New users might miss the true magic if we stick to old language. So why not call them “AI assistants,” “LLM-powered assistants,” or just “AI” instead? It would help everyone see the progress, and show how Mozilla’s still leading, not just catching up.

I’ll leave it open for discussion, but I hope others feel this shift too. Language shapes how we see these things—and sometimes it takes a Singular Fella (or maybe two) to nudge the world past old memes. Thanks for hearing me out, and here’s to a future where our assistants, and our words, keep getting smarter.

I have spent hours with Tech department and digital assistand department at Directv. Today they are telling me as long as I use Firefox I will be unable to access my account. I have paid to have my computer checked out and was told that it was updated and the system was working fine. How to I get Directv to recognize my system?

I am using version 88.0 and browser, both outdated and not supported. How do I update to current version and update browser? I am 80 yrs old and not computer literate, please keep it simple. Also, I am alone, not help available. Thank you

This wave of so-called AI (really nothing of the sort) is a nightmare for security, usability, performance and efficiency and if you keep forcing it on us I'll be jumping ship, probably for whichever fork excising it all gets popular.

I've been using first the Mozilla suite and then Firefox (since it was called Firebird, even) for twenty years now, don't do this to the browser I love.

I have Privacy & Security set to Strict with Cookies and Site Data deleted when the browser is closed with only 3 sites in the exclusion tab. I also use a VPN to assist with masking and for connections to defined systems and as part of that I will randomly set it to different countries 'because I can'.

I was looking at the website for the current Rugby World Cup (https://www.rugbyworldcup.com) but it was showing the wrong times for the matches. A little digging showed it had remembered my location from some point last week when the VPN was active and set to Iceland.

There is nothing I can find in my browser settings to permit this and I would appreciate pointers to check further since one of the reasons I have set the higher level of restrictions in my browser is to stop this kind of activity from websites.

Only on firefox, the music on apple music keeps changing volume. I can hear it sound fine for a second but then it changes the volume to around half of what its meant to be. I dont see any settings to change it, its fine on other browsers, im genuinely unsure of what to do.
