Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

Selecting "Help About Firefox" causes the window to appear but this window then freezes with no information. It is possible to close the window and continue with Firefox. This happen nearly always but occasionally works correctly. Current Firefox version is 146.0 but the problem is not limited this version. System is Kubuntu 24.04, KDE Plasma Version 5.27.12 and QT Version 5.15.13 I have tried several things. Deleting the .Moziila folder will permit the window to work once but after a restart stops working. Any new things to try would be appreciated.

I have 3 devices connected to Mozilla account, 2 smartphones and 1 PC and NONE of them are syncing properly, bookmarks sync perfectly and everything else fails miserably. Some part of history does sync but nowhere near the full history. Syncing of open tabs is *completely* broken.

I've installed Nightly the same way I have for years on my latest Fedora 33 install—i.e., download tarball, extract into /opt, set appropriate chmod and chown, make .desktop file, etc.—but certain videos certain videos on certain sites refuse to play. A Fedora discussion discussion led me to think it's how Fedora 33 may sandbox apps; I haven't yet had any hits on solutions in the Fedora groups, so I thought I'd ask here, since I can't be the only one with this issue.

Any help would be greatly appreciated!

Hi All,

I've set Firefox to open PDFs in the default system application (I'm on Linux, KDE, Firefox 146). With previous versions it worked fine. Now, it won't open the file; instead it shows a popup that I have to click to open the file.

Is there a setting I can tweak to get the old behavior back?

Thanks

GI

Hello again guys,

when I play a video in Firefox, it doesn't keep the screen on.

I need this accessibility feature.

This happens, at least, with Debian 12's Firefox (uptodate), like over 1 year now.

Please help with that too.

Thanks in advance!

Regards from Germany, Johannes

I had so many instances of firefox and tabs that i decided i must organize them on tabgroups, i read they were secure enough and would be restored along with open tabs on new session. But after restarting all my "close and save" tab groups are missing! are they still saved? how can i recover them?

If Firefox becomes an "AI browser" as it's new CEO says I will switch to another browser. The privacy and environmental problems alone are enough for me to warrant this change, to say nothing of how it's slowing the browser itself down and making it worse. I'm sick and tired of AI shoving itself into every single aspect of life, taking things that already worked fine on their own and making them worse for no reason, in addition to ruining the planet and encroaching more and more on the privacy of everyday folks like myself. Anthony Enzor-DeMeo's insistence that we should "trust" this hypothetical version of the browser is frankly sickening, and everyone involved in this scam should be ashamed.

Recently upgraded to version 146.0 on Linux (Mint, Cinnamon)

YouTube will work fine when I first start the browser. Eventually videos will stop displaying and sidebar links will not be active.

From a separate forum article I cleared all site data and restarted Firefox. That fixes the problem for about 4 or 5 videos, then you need to rinse/repeat.

The latest incident seems to have been triggered when I tried to watch a video embedded in an X (Twitter) post. That failed. And the YT failed as a whole. X was open in a separate tab container at the time.

While I have both Privacy Badger and uBlock Origin installed, both are deactivated for YouTube.

See the attached images. The video is just not displaying, though the screen is reserving space for the player.

Both/all videos I have tested do work in Chromium.

I've been doing free advertising for Firefox for years, successfully convincing friends, family and coworkers to reject chromium browsers and make the difficult choice to switch browsers and get use to a new interface on Firefox. I know most people like me are able to do this by touting that Firefox actually cares about keeping your data private and allowing users to opt in to many "features" that chromium browsers have you opt out of. Unfortunately with the recent inclusion of AI settings that have been turned on by default and hidden under layers of setting menus, it looks like Firefox is turning to the same tactics we came here to escape. If this trend coninues, I won't be able to in good concious recommend this browser to others, and might as well just switch back to chrome which more websites have better support for. I hope the company makes the right decision and keeps AI out of Firefox

Just wanted to add my voice to the complaints about further AI being added to firefox. Firefox as a browser is a refuge from the enshittification of the internet as a whole, with it being one of the few non-chromium browser options, please dont join in the effort to force AI on everyone. At the very least it shouldnt take multiple options to disable AI in my browser. But at best I would love to see firefox development focused on performance rather than more AI bullshit that only CEO's want.

I come, trying to manage my disappointment and anger, to say only one thing: I love Firefox, it (still) has the best UX of any modern browser. And part of that is that it has NO AI malware built into it. The recent statements from the CEO regarding the implementation of AI into the browser is extremely disappointing, to the point of it feeling like a personal betrayal, and will only make me (and a lot of other people) just completely abandon it. And don't kid yourselves, your user base never was so low, and that user base only like this browser specifically because it has no malware built into it, because of the privacy and open nature you had before this debacle. You're shooting yourselves on booth feet and an arm with a shotgun. I don't trust you as a company anymore at all; you just achieved the complete opposite of what you said you wanted. If you just made use of reverse psychology and was that's your actual goal, congrats. This company quite literally couldn't have elected a worse person to be chief executive.

Win 11 stopped working on my Lenoovo Yoga due to bitlocker key requirement that does not exist I'm in the process of installing Ubuntu during the installation something went wrong "system program problem detected" which stopped the installation

Hello everybody, i hope you are having a great day!. I have a problem with Youtube about the frames drops, in 1080p60fps i have drops but in 1080p normal don't. For system operative i'm using Fedora 43. And the Firefox version is the 145.0.1 64 bits. My specs are low: Intel i5 6200u with his integrated graphics (Intel HD 520) Already installed the extension h264ify, and i think i have all the correct drivers and codecs from the rpmfusion (ffmpeg, mesa freeworld) If u need more detail and information i can give it to you. Thanks for anyone that is interested in help me.

I know I am far from the first person to bring this up, but it is absolutely horrid how a browser that is supposed to be one of the better options for privacy is starting to integrate more and more unwanted AI "features". None of us want this, nobody asked for this. Generative AI (including LLMs like ChatGPT and its equivalents) is horrific to even try to get a correct answer out of. It's simply processing your input and guessing what you want to hear in its output. It doesn't give facts, it doesn't help the user experience, it just makes things worse.

Every single time a new AI...thing is added, I have to go find a way to turn it off. If this keeps going, I cannot see a future where Firefox is a viable option for secure browsing. If anything, it may actually become on-par with or, dare I say worse than Google Chrome.

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.
