New firefox update - problems?

anyone else having problems with firefox after the last update?

i am unable to launch the browser at all.

Uninstall it and reinstall. You shouldn’t lose your profile (settings).

If reinstalling doesn’t work you might want to try to start in safe mode (instructions here) to see if some setting or extension is causing an issue. It’s possible that the section titled “Firefox previously worked” on this page might also be useful.

download the install directly from the main site, dont let the program do the update
i had the same problem
