The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again. I get this message when I try to install FF 7 and FF is NOT running! Help
Get this message everytime I try to upgrade from FF6 to 7. I have rebooted and tried again twice and still nothing. Shortly after I get the failed to install message FF6 starts up by itself. On top of all this some, if not all web pages, do not complete. Google Chrome works just fine. No fix for FF problems I will uninstall and use Google Chrome
