2 DAYS AGO I got an XUL error notice in my UP TO DATE Firefox. Tried turning on or off at times hours apart no use. Getting by with other browsers in the meantime. But today At about 1:40 PM CDLST 15 August 2024 my computer locked up completely. Several dialog boxes stacked up and mouse and keyboard were ineffective it gave a virus name which I did not write down and a purported Microsoft number to call but I ignored it. Turned off my computer turned on and ran scan with Malwarebytes software NO INDICATION OF INCIDENT The help page advice for XUL does not have the assurance NOTED AT BOTTOM. IS THE FOLLOWING TRUE FOR ALL REMEDIES INVOLVING UNINSTALLING AND REINSTALLING FIREFOX? INCLUDING XUL ERRORS? ASSURANCE The solution is to remove the Firefox program and then reinstall Firefox. (This will not remove your passwords, bookmarks or other user data and settings which are stored in a separate profiles folder.) Lately I have been having low memory warnings, but still have some things I can dump to make room.
