Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

NB - For the past half a year I have to sometimes right click to interact with them, anyway

Effectively, I will interact with the extension at the most basic, normal level on something that has interactive elements like a dropdown menu, or basic options.

I will click / right click on the icon and the highlight will appear, then that's it ... the browser then crashes and does not recover. :(

What's worse is that I have to Force Quit and when I restart there is no crash report to send to Moz.

I am just wondering if other Linux users have experienced similar issues.

The attached image is taken at the moment before the 'Force Quit' dialogue opens up in Debian 12 Gnome (Wayland) ...

I have Hardware Acceleration on.

I am about to start testing with it off, but I work from the browser, and do not want performance compromises. So that is (at best) a work-around, and certainly is not a fix.

I'm on version 147.0.2 (64-bit) which would appear to be from the Mozilla Firefox Debian Package mozilla-deb - 1.0 install/repo/whatever ... and the PC specs are: Processor: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Memory: 32705MB (11893MB used) Resolution: 7680x2358 pixels OpenGL Renderer: Quadro RTX 3000/PCIe/SSE2

These are my media. prefs ... but ... I doubt that it is relevant: media.ffmpeg.allow-openh264 true media.ffmpeg.customized-buffer-allocation true media.ffmpeg.disable-software-fallback false media.ffmpeg.enabled true media.ffmpeg.encoder.cpu-used 7 media.ffmpeg.encoder.enabled true media.ffmpeg.encoder.quantizer-max 35 media.ffmpeg.encoder.quantizer-min 10 media.ffmpeg.vaapi.force-surface-zero-copy 2

I'm reading https://support.mozilla.org/en-US/kb/mozillacrashreporter#w_when-firefox-crashes

Firefox crashes but I have never seen the crash reporter on my 6.18.10-200.fc43.x86_64 Fedora 43 system with budgie-desktop 10.9.3

Is the crash reporter discontinued?

• OS: Debian (trixie)
• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

My firefox has been closing while I am away from my computers. I have a few computer running linux (Ubuntu 24.04) and one in mac osx (Big Sur). Usually, I can start firefox and it will remember my tabs which is annoying but still manageable. However, once in a while, (which happened yesterday), all the firefox closed on all the computers and it forgot my tabs when I start firefox again.

I have already set app.update.auto to false on all of the firefox instance prior to this incident to avoid firefox update would close out firefox itself. So if anyone has any idea of what to check to see why firefox keep closing and/or why once in a while it will not remember my tabs, I would really appreciate it.

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.

I had an issue where my browser disappeared. Here are specifics for my installation.

Name Firefox Version 142.0.1 Build ID 20250827004350 Distribution ID raspberrypios User Agent Mozilla/5.0 (X11; Linux x86_64; rv:142.0) Gecko/20100101 Firefox/142.0 OS Linux 6.12.62+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.62-1+rpt1~bookworm (2026-01-19)

I relaunched and then restored previous session. After that, I searched open tabs, but when I selected a tab that was reported to be opened,  it was not restored. I went to troubleshooting mode and it worked fine suggesting some issue with an extension.  What, if any logs could I capture to help debug? thanks

I use Linux Mint and I have been experiencing numerous system crashes involving Firefox which requires a cold boot. What is the problem? How can I debug this? Are you getting crash reports?’

This happens several times a week. It has happened continuously tonight since installing the latest update via the Software Manager.

The program causes a total freeze of the OS. All other running programs and all input sources. I have no choice but to shut down via the power button on the tower.

Mint generates crash reports but I have no way to determine if they are being sent to Mozilla.

Firefox for Linux does not provide a troubleshooting system like it does on Windows. Neither does Mint.

I studied Computer Science in the 80s when Firefox was known as Navigator. I learned C and the Unix OS, but since then I became a psychologist, and don't remember too much of the Com Sci stuff I learned and I don't think Mint allows user modifications anyway.

What can be done to fix this? I don't have the Benjamins to buy a new Windows to replace the Linux, nor do I want to.
