Decided to switch to firefox from brave. Am completely unable to run Firefox. Doesn't even show up in task manager. I have one split second of a window, then it vanishes. Tried safe mode, tried running as admin, nothing. Brave and edge work, and I even downloaded opera to see if it would mess that up too, but opera booted fine. Running Windows 10 22H2, OS build 19045.3324. Any help is appreciated.

Chosen solution

Reinstall the Visual C++ Redistributable.

Parental controls in your Microsoft account can block certain browsers from starting. Does it still happen if you rename firefox.exe to something else?
