Firefox Developer Edition - Windows 11 Issue
Ever since upgrading to windows 11 firefox developer edition will not work for me at all.
I have reinstalled it multiple times now and every single time its the same thing, after a fresh install I can open the browser, use it once, close the browser and then it breaks and I am unable to use it again - sometimes i cant even open it up again it creates a background process in the task manager but never appears.
- - None of the tabs will load anything at all including any of the settings pages or debug/troubleshooting page (about:<page>) - its like it doesnt even attempt to load anything its completely unresponsive
- - Clicking on any buttons in firefox/options menu do nothing
- - If i close it i see between 2-10 firefox processes appear in my task manager which i have to go through and end each task before i am able to open the browser up again and even then that doesnt always work.
- - Because it opens a bunch of processes when you close the browser and this prevents it from re-opening it is not possible to put it into troubleshooting mode
- - Even after a fresh install (described below) after re-installing the browser it always opens for the first time with a message saying that 'I have reinstalled firefox would i like to refresh the browser' with a button to refresh - If i click this refresh button it instantly breaks it
In order to fix this I have to completely remove firefox from my machine including:
- - Everything in my users folder
- - Everything in program files/programdata
- - Search my C:\ drive and remove all traces of mozilla/firefox i can find
- - Clear all temp files
- - Run a disk cleanup
- - Restart my machine
Before i can attempt to install firefox again. If i dont do this after i reinstall it opens firefox up in exactly the same state it was in before i uninstalled it, same tabs open & completely unresponsive.

So I seem to have fixed the issue by doing the following:
- Uninstall firefox through control panel
- Delete Mozilla folders in /Users/<username>/Appdata -> Local/LocalLow/Roaming
- Delete Mozilla folders in Program Files/ProgramData
- Clear temp files
- Run disk cleanup
- Windows Key + R -> regedit -> Computer\HKEY_LOCAL_MACHINE\Software -> Delete Mozilla/mozilla.org/MozillaPlugins entries from the registry
- Restart machine
- Re-install firefox

Have you tried Windows in Safe Mode?
Edition Windows 11 Pro Version 21H2 Installed on 03-Jul-21 OS build 22000.466 Experience Windows Feature Experience Pack 1000.22000.466.0

Yeah still broke in safe mode!
Boot the computer in Windows Safe Mode with network support to see if that has effect.
I don't know whether this is an issue on Windows 11, but on Windows 10:
Sometimes program installers and uninstallers mess with certain shared Microsoft files, especially the VCRUNTIME140_1.DLL file. Missing that folder can cripple Firefox from the address bar down.
To rule out that issue, you can (re)run Microsoft's installer for the VC Runtime files:
(B) In the "Visual Studio 2015, 2017, 2019, and 2022" section of the article, download the installer for your system:
- 64-bit Windows: the "X64" download
- 32-bit Windows: the "X86" download
(C) Run that installer and restart Windows.
Any improvement?

Thanks for your response I've tried this and unfortunately its still not working. Is there anywhere i can view logs for firefox? Ive looked in windows event viewer but im not getting anything show up in there.
I would try Process Monitor to get an idea of what's crashing Firefox. https://docs.microsoft.com/en-us/sysinternals/downloads/procmon This video should help with the basic logging of the issue and then you can check to see what happened when Firefox crashed. https://www.youtube.com/watch?v=ojUFjE00prA
You can create a new profile as a quick test to see if your current profile is causing the problem.
See "Creating a profile":
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
