Just an FYI to maybe save some others some time and grief. I just had Firefox randomly decide that most of my addons were no longer compatible and has shut them all down. This is a world wide screwup from Mozilla. Anyway if anyone else HAS noticed it there are discussion here:

and here
It'll get fixed shortly. Life goes on.
