Uninstall Firefox Add-ons

Add ability to uninstall, not just disable, Norton add-ons in Firefox. This has been requested by many users in various threads, and would be useful when there is a conflict between the add-ons and Firefox, as sometimes happens when Firefox is upgraded to the latest version. Ideally there would also be an option in settings to reinstall the add-ons on reboot, which would eliminate the need to uninstall and reinstall Norton to get them back.
