"Firefox has stopped working" whenever I open it.


Today I tried to use firefox for the first time in a few months (as chrome wasn't working for something). When I opened it, the Windows "Firefox has stopped working", "Check online for a solution and close the program" or "Close the program" window pops up. It pops up before the firefox window even opens or anything. I reinstalled the newest version and it is still doing it. Can anyone help? Thanks!

I don't know as I can't open it.

Try Restart Firefox in Safe Mode and check it again.
