That’s different than a System Restore to a Restore point through Help and Support menu. (Start, Help & Support...)
Well I pulled out the current FF and tried to install an earlier version but it won’t connect. I did the restore and it still does the same thing - block me from YouTube, Facebook, and the add-on’s from FF ... strangely though, I have a notebook I carry with me and it’s a mirror of my desktop and it runs okay .... ????
Don’t know what happened or what I did but now things are working okay - can get to YouTube and Facebook now. Also the drop down to get to add-on’s work now as well. Go figger?????
