After upgrade to Windows 11, Firefox won't open anymore.
Hi, I've upgraded to Windows 11 today and couldn't open Firefox since. Things I've already tried:
- Reinstall Firefox and delete all old files (Appdata & Program files)
- sfc /scannow and DISM.exe /Online /Cleanup-image /Restorehealth
- Windows compatibilty mode
- Firefox Troubleshoot mode won't open either
- ipconfig /release & /flushdns & /renew
- netsh int ip reset & netsh winsock reset
When opening Firefox in any way, i get a white window/just the window border which immediatly closes. When trying to start troubleshoot mode, the small window has the same issue.
I also checked the crashlogs and none were generated. The Windows event-logger also has no entries.
BTW: Here is a video of whats happening: https://youtu.be/AJP4rqZFxlY
I have no idea what to do - send help please.

Your Microsoft account may have parental controls enabled which limits what browsers you can use, you could try to get this limitation removed or create a new account. Renaming firefox.exe to something else can get it working but this will break DRM protected videos.

Did you recently uninstall an application that was using Visual C+ runtime components?
You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.
See "Visual Studio 2015, 2017, 2019, and 2022":
Download the latest vc_redist.x64 and vc_redist.x86 files.
You need to reboot the computer.

This didn't help - i just recently installed it and repairing it didn't do anything either.

My hate for Microsoft is steadily increasing since I started studying software engineering. This is the reason why - the goddamn family safety suddenly kicked in with the upgrade. I had to configure that when i still was underage and years later it decides "no firefox for u anymore".
Goddamn it, thank you for solving my problem.
