I can't open firefox. message says "firefox quit unexpectedly" and it won't reload. I tried Force Quit. I tried restarting my computer. I tried completely shutting computer down and restarting. It happened very suddenly yesterday.

Note that the user is on Mac OS.

Try to start Firefox in Troubleshoot Mode to see if that works.

Try to reinstall Firefox in case something went wrong with updating and drag the current Firefox application to the Trash.

You can find the full installer of the current Firefox release (125.0.1) in all languages and all operating systems here:
