I have the latest update on Firefox and at times it even happens with Chrome. I am wondering would the mouse I am using have anything to do with it? It is one of those laser Logitech that plugs in. I just ordered a simple wireless mouse a few days ago and I am hoping that is the problem. It seems when I pick up the mouse to move the screen, it goes away and I can not even get to the bottom to save anything. I am so stupid when it comes to this stuff but at my age I am lucky I am still alive, much less have a computer problem.
