Mozilla Firefox no longer starts on Window 10 Desktop

I have used Firefox on this Windows 10 desktop computer for at least 6 months with no problems. I have it set as my default browser.

When I say it "does not start" I mean the hourglass is shown for a few seconds, then nothing. Task Manager does not show Firefox running.

Since about 5 days ago it will not start when I click its icon on my taskbar or when I click on a link in an email. Both of these used to work. I have also typed Firefox into the Windows search box and clicked the icon then shown, but it does not start.

I have googled the problem and tried a number of things, such as re-installing.

When I do Windows-button & R to get the Run box, enter “firefox.exe -P” and click OK, the profile program does not start.

When I run "Firefox Installer.exe" it goes through process and ends with Firefox open. That is how I was able to get in to get the Troubleshooting Information. However, I do not want to start it this way all the time, and it would not work on links in emails.

I could not find how to add Tags.

Thanks.

Have you tried Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

How about trying Windows in Safe Mode to see if you have the same issues? https://www.google.com/search?client=firefox-b-1-d&q=Windows+in+Safe+Mode

I assume this is the current version Firefox 97.0.
