I had to emergency shut down due to a storm. After the reboot of my Mac Firefox will not open, even while holding down power key. This is a constant problem I run into and am not finding a solution. I'm having to use safari to get to you. All I get is a spinning wheel/firefox is not responding and I have to force quit. All I have ever used is Mozilla but am going to have to give up and use safari. It at least works.

Have you tried Firefox's Troubleshoot Mode? Diagnose Firefox issues using Troubleshoot Mode

It should get Firefox started again. Please try it & let us know if you were successful. If not, I'll have to think of what else could be causing Firefox to be so broken. It could be one of the main installation files were damaged. If so, you might try reinstalling Firefox again to see if it can fix the corrupted or missing file. Reinstall from here: https://www.mozilla.org/en-US/firefox/new/

It is possible that some files in the profile folder got corrupted.

You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

You can find "Clear the startup cache..." on the "Help -> More Troubleshooting Information" (about:support) page. https://support.mozilla.org/en-US/kb/use-troubleshooting-information-page-fix-firefox
