I used Firefox for Years without Problem and Have no idea why it doesn't work anymore. Removing and reinstalling Firefox didn't help.

Hi sallythecat, sorry to hear about this problem.

At least two issues have been identified for startup crashes in Firefox 71 on Windows:

(1) Old files from Comodo security software

Firefox may crash instantly with older versions of this file present:

C:\Windows\system32\iseGuard64.dll

(2) Old Logitech camera driver software

I don't know the file name to look for but you would want to update the software. https://support.mozilla.org/questions/1274407

Thank you very much for your help.

Deleting the iseGuard64.dll did the trick
