I just got this new computer today, and I decide to install Firefox on it, only to find that it crashes when you attempt to open it. It will flash for just a millisecond before closing itself. It is a fresh install of Windows, and I have ran all of the troubleshooting on the Windows side to check for corruption and its all correct. I have even contacted Microsoft support to see if this is a compatibility issue. They suggested I contact Firefox support. Any help is greatly appreciated!

There are no other programs on the PC other than Firefox

Update: I did a clean install of windows again, and it works. However, the moment I sign into my Microsoft account on the computer, Firefox refuses to open.
