Firefox refuses to open

Ive uninstalled it multiple times, done just about everything suggested online, and even got it working for a bit off the Microsoft store. But for some reason, my desktop Firefox will not open at all.

Hello,

The issue may be fixed with the latest 140.0.1 release. Please update your Firefox (you can just download the Firefox installer and run it when the browser is closed) and let us know whether the problem persists.
