I was using firefox and all was working well. It was Jan. 13,2012. Then for no reason while I was playing a game on facebook the screen went very large, then small and then stopped on very large,where very little fit on the screen. Every other page including all of facebook works fine. NOT the games. I tried uninstalling Mozilla and reinstalling, then it kept saying that it crashed and would not come back. I sent reports but heard nothing. Today i uninstalled again and now it works but not the games. And ideas?
