FF for Linux Mint mint-001 1.0 FF closes in just a couple of minutes, even with one open tab and nothing clicked or typed. FF crashes even in "Troublshooting Mode". "about.crashes" lists no crash reports Using Task Monitor to view system vitals, I discovered that while CPU usage by FF is very low, memory usage rises linearly over a couple of minutes. System memory available is 31.0 Gb. When FF usage reaches 30.7 Gb, FF crashes. No other browser or program has issues.

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.

I am not a computer nerd I can only describe what is happening. I am addicted to puzzles and do them every day but am encountering problems nearly every day this week of the puzzle pieces not responding to mouse and have to shut down the computer. At other times I am kicked out of the site and returned to my desk top. No amount of trying to then get back into firefox is useless until much later on. Why is this happening?

Hello, Firefox has been giving me some troubles lately and I can't figure out how to resolve the problem. Since I haven't found any way to consistently reproduce crashes, it is very hard for me to tell if Troubleshoot Mode also experiences the crashes, and the time I can spend doing that is very limited. As previously stated, it is very inconsistent, but relatively frequent, sometimes it crashes very soon and several times in a day, others it doesn’t at all. Sometimes it crashes with several tabs open, sometimes with only one; sometimes it crashes while using a webapp, others it does so on the newspaper page. It might be more frequent while there are Electron Webapps open, but it's more a hunch than anything, since sometimes it happens without those. I have followed the steps in: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-crashes-closing-or-quitting Been unable to find the cause so far. Here is the crash report ID from the latest crash: bp-60cd6ea9-9bd1-411d-a0ca-2f6fd0260415

The crash report does include information on my system, but please let me know if any other information might be useful.

Thank you very much in advance and I hope you're having a great day.

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

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.

Dear Mozilla Support Team,

I have downloaded Firefox through the official website and I have installed it through the terminal for Chromebook's Debian Linux.

I have a Chromebook c214ma with a Intel Celeron 4020 with 4 GB ram every single browser on my machine works properly just Firefox keeps closing and crashing

Kindly fix this issue

Regards,

Pranav

• 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

Hi,

At some point in the last couple of weeks, I've started running into very frequent crashes running Firefox in the Linux container on my Chromebook. It previously worked well, but is now unusable. I'm now running Firefox version 147.0.3 on Chrome version 144.0.7559.167. This is after I did a clean reinstall of Firefox using flatpak, which didn't help. It seems like it often happens when my mouse hovers over a browser tab or icon (eg account, extensions, hamburger). Other quirky display behaviour, which mayor may not related, is that videos are often not working (eg Youtube, BBC), and various browser windows (eg when selecting Manage Bookmarks, or restarting in safe mode), open a small size-reduced window. Latest crash reports below -

Thanks for any suggestions.

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?

I've been using Firefox on Linux since it was Nautilus. Currently running EasyOS Linux Daedalus and Excalibur on different Lenovo ThinkCentre Tiny Core i3-8100t boxes and different drives: A good Samsung SSD and two good flashdrives. 32G new RAM installed on each box. I've been using these boxes for over a year. For the last month or so, ever since updating to v. 146 my tabs have been crashing like crazy! I don't normally have more than 10 tabs open at once. But now, as soon as I open a 5th tab it crashes.

I'm running Top to watch CPU and RAM usage. I see nothing unusual. I've rebooted. Disabled all add-ons and run in Troubleshoot mode. Tabs still crash. My only add-ons are uBlock Origin, Temporary Containers and Dark Mode. It happens whether I have hardware acceleration turned on or off. I don't know what else to try. Here are my most recent crash reports. I hope you can figure out the problem. Thank you so much!

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

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!

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.

Crash submitted, ID = 320cc808-4505-4cba-6e0f-9f2c2955d007 Still happens in troubleshoot mode. Still happens with extensions disabled (Ublock origin, Proton Pass) Started happening since Dec. 5, 2025 System is current with all Debian?Ubuntu updates installed (daily refreshes) Linux Kernel 6.8 on Lenovo Yoga i7 (ca. 2022) with Intel i5 & Intel graphics

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan
