There are now 2 Firefox installed (1 safe). Don't know why. Neither will open. Help?
My husband's laptop. I assume I should uninstall all Mozilla and then reinstall, but just need to make sure. The good news is that he has virtually no data on laptop whatsoever.
No - SafeMode is a troubleshooting mode and having two Start Menu items is normal for Firefox 3.6 and earlier versions. Firefox 4.0 and newer don't do it that way.
A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
