Firefox crashes repeatedly on startup, even using safe mode fails 9 times in 10. Multiple crash reports submitted.
Firefox is the only application affected (latest 107.0.1, Windows 11 pro latest updates). I have updated all drivers, run system and memory checks, uninstalled deleted remaining files and registry settings, twice actually all to no avail.
I have recently changed ISP but cannot see how that affects just Firefox (Chrome/Opera/Edge all work) and also moved to Bit Defender antivirus. Here I think I saw startup installations in Chrome etc for bit defender but never for Firefox. I have tried turning off all virus web protection still no joy.
I have looked briefly at the crash reports but with my level of expertise I can see no common crash reason.
I have had no add-ins installed for last week while trying to get this to work again. I have used Firefox for years and have no wish to move to another browser but this situation is driving me nuts.
If there is anybody out there with any ideas on next steps I could take?
Cheers Mike

Ok I have found the cause. Its because I have Explorer patcher installed. This dll ExplorerPatcher.amd64.dll is mentioned in the crash data. I've uninstalled the program and Firefox is again stable.
Since I really like Explorer Patcher if somebody could tell me when the issue is fixed I would appreciate it.
Cheers Mike

We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
- On the keyboard, press [Windows] The image "Windows key" does not exist. + [R]. This should bring up a Run window that contains a text field.
- In that text field, type %APPDATA% and press Enter. An explorer window should open.
- From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
- Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
- Open the most recent 5 files with a text editor and copy the IDs.
- Paste each ID with bp- into the reply window on the forums.
Thanks in advance!

I forgot to back up the crashes from the previous week when I deleted and reinstalled so I cannot give you the original crash reports.

Hi,
I don't know if this helps but looking through windows system log there seems to be a lot of
LSA package is not signed as expected. This can cause unexpected behaviour with Credential Guard.
PackageName: kerberos
related warnings on startup.
This appears to be a microsoft bug from last update. I'm trying to find a workaround to see if it affects Firefox in any way.
Lost previous list on edit of previous list with a report from today. Repeat
