I downloaded the add-ons and restarted FF. I then noticed that McAfee Site Advisor was missing. I checked the add-on list and saw a message stating that the Site Advisor add-on would be installed when FF was restarted,even though I had just done a restart. I restarted again but I got just the same result. After another restart with no change I tried to cancel the update but nothing happened. I can't cancel the update and the message remains.So I can't install or cancel the update. What now?
FF support suggested removing the update download but it couldn't be found. I reinstalled FF following their suggested procedure but that made no difference. I removed all traces of FF and reinstalled again. All now OK.
