In the last week or so, maybe since installing the new version of Firefox, I have been having problems in Facebook, where it will just crash/hang, especially if I go full screen in a game & I have to command/option/esc to get out. I went in to delete cookies & cache & checked that my plug-ins were up to date & they were fine, except for Java, but since I have a Mac, my Java is updated through the computer. Since this has never caused a problem before, I think it's unrelated. Anyway, does anyone know why Firefox is hanging or crashing all of a sudden in Facebook, especially in games/full screen mode? Thanks..
