I received an alert about a virus from Firefox. This would have been on Sunday 7/4. I figured it was some sort of a scam and don't remember what exactly I clicked, but it was something to the affect that I did not want it to do whatever it was that it wanted to remove the virus. I uninstalled FireFox and have tried reinstalling it numerous times and it will not launch/open at all, it will "bounce" once and sit in the dock. I have a MacBook running iOS Big Sur. Any help provided needs to be very specific in steps and instructions so I may understand what I need to do to rectify the situation. I need my FireFox back.

First, let's check your system.

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed free to use malware scanners. Each works differently. If one program misses something, another may pick it up.

Note that you should never click a button in such a scam alert, but simply close the tab or kill the Firefox application and not restore the offending tab on the next start.
