I have updated FF and my WIN7 on this computer This FF will not sync and the under the options menu and under sync and manage occunt- it only has the email sign in feature- not the sync this machine option. I tried to install one of my favorite ass-in (new tab plus) and it tells me "This add-on has been disabled by an administrator." However I am the admin to this computer- I tried uninstalling and reinstalling to no avail- I have tried restarting in safe mode and still get the same errors messages What else can I do to get the FF on this computer to work as it does on my other computers
