- Had 3 windows open with numerous tabs and tab groups - Firefox sync was enabled, as well as a 2-3 plugins AFAIK - Version installed is latest as of this writing 139.0.4 - Initial crash caused by opening and quickly closing (IF that succeeded before crash) a onedrive share link - Cannot start firefox any more, also not in safe mode - the only thing that works is launching it with a fresh profile.

The report ID is bp-a8c824fc-a7fb-4290-a72b-b63160250620

Ideally I can resolve this without needing to refresh or start over with a new profile

I launch Firefox from a shortcut in the QuickLaunch bar. I need to double-click that to get a response. But then TWO instances of Firefox open, and I have to close one - which seems a waste of time and effort over and over and over. My system is x32Win10ProV22H2. How to get just one instance ?

As title: after running updates, Firefox consistently crashes when launching.

To give more concrete details:

-Running on Linux, specifically KDE Fedora 42. Firefox was updated to 142 from 141, alongside various other updates. -When launching Firefox from any source (directly, through a link, through the terminal etc.), the only window that appears is the crash reporter. -This issue occurs when launching in safe mode. Removing and reinstalling Firefox, including deleting the entire .mozilla folder in Home at the same time does not resolve the issue. I am unable to test rolling Firefox back to 141. -When attempting to launch from the terminal (safe mode or otherwise), the following is output (personal info redacted):


restorecon: SELinux: Could not get canonical path for /home/[username]/.mozilla/firefox/*/gmp-widevinecdm/* restorecon: No such file or directory.

/usr/include/c++/15/array:210: constexpr std::array<_Tp, _Nm>::value_type& std::array<_Tp, _Nm>::operator[](size_type) [with _Tp = HeaderBarButtonType; long unsigned int _Nm = 3; reference = HeaderBarButtonType&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.

Redirecting call to abort() to mozalloc_abort

[ExceptionHandler generates a minidump etc.]

Gtk-Message: [timestamp]: Failed to load module "appmenu-gtk-module"


(I would note that to the best of my knowledge I had not included a plugin for decoding widevine in my Firefox setup, and certainly the Firefox 141 instance on the device being used to write this post (same OS) does not include it) -The crash files in the .mozilla folder, meanwhile, consistently list a segfault at address 0x0.

Any advice on diagnosing/solving this issue would be greatly appreciated. Let me know if there's any other information that would be helpful.

If it would be more appropriate, I could report this through Mozilla's bugzilla instance, but given the issue seems to be very niche (Fedora's ABRT shows a total of 5 unique affected users in the last few days) I am unsure whether flagging this there would be appropriate.

When I try to open Firefox it opens hundreds of crash reporter dialogue boxes and makes my computer slow to a halt, only restarting my computer can stop the onslaught. Resolving a dialogue/close all doesn't help.

I've tried holding shift to start in troubleshoot mode, but it just opens the crash boxes rather than the 'do you want to start in troubleshoot' box.

I've run a scan with Malwarebytes, no hits, and Windows says there's no updates for me. I can't see any specific crash number, the 'submit' file in my Crash Reports folder says this:

I had two profiles, was in the process of trying to learn how to use the 2nd profile (as seen in the link below), which I still have no answer for. Somehow, maybe I held down SHIFT for too long and clicked on something by accident, idk, but somehow, I ended up REFRESHING the 2nd profile, causing it to delete everything I had done with it, and it backed up the old profile onto my desktop in the process. I figured I could just simply delete the new profile folder it had created and put back my old profile in the profile folder, but now, Firefox will not open at all, saying "Your Firefox profile cannot be loaded. It may be missing or inaccessible." How do I get it to recognize the profile folders again? OMG, I'm using Microsoft Edge, please, get me out of this!

Hi, my Machine updated from 140.0.4 to 141.0 since then I cannot start up Firefox anymore. On startup after a short pause the Crash Reporter shows up - interestingly the Crash Reporter may enter a endless loop and opens up multiple times. While that the CPU load is at 100%. I tried

  • `firefox --safe-mode`
  • `firefox --ProfileManager`

as well, for those I get the same behavior. I tried downgrading to 140.0.4 - after that a profile dialog shows up which tells me that a new profile needs to be created due to a downgrade. After that Firefox comes up fine with the new vanilla profile. IF Firefox updates to 141.0 (in background) the next startup with the vanilla profile doesn't work gain. Which brings me back to the initial problem.

Workaround for now:

  • download 140.0.4
  • create a fresh profile
  • immediately disable auto update
  • live with the empty profile

My environment:

Summary - Firefox crashes repeatedly. yesterday, I decided to switch to Firefox after using Chrome for a while. it worked fine and I synced my data from Chrome. today, at some point I noticed Firefox is no longer open in my taskbar. I decided to reopen it - it crashed. since that moment it has never worked again. I tried launching it in safe mode (firefox.exe -safe-mode), didn't work. tried reinstalling it, didn't work. manually deleted the files from C:\Program Files and AppData, installed Firefox again, didn't work. reinstalled gpu drivers, didn't work. sfc /scannow-ed, you guessed it - still crashes. what else could I possibly try? please help.

I'm trying to install Firefox on my work computer (ARM64 version), but when I do I'm getting the crash report window at the end of the installation process (multiple times in a row), if I try to open the browser (only once), and during the uninstallation process (also multiple times in a row). I've tried a clean reinstall multiple times, including deleting the folders from program files, %APPDATA%, and all registry entries I could find (HKEY_CURRENT_USER>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node).

I've contacted IT and they don't seem to think anything pre-installed should be affecting this. I'm unable to get a crash ID as I'm unable to even start the browser - all I get is the Firefox crash reporter, immediately. Is someone able to help me figure out why I can't get this working?

Hi, We are using Horizon VDI terminal server. Firefox is installed on these servers. Some users get Firefox is already running but is not responding error. Ending Firefox via task manager does not work. I log off the user and have them log in again, but it does not work.

When I check, I see that the user's profile file cannot be created on any terminal server.

Is there a solution to this problem?
