I am running Windows7 Home Premium. I can play You Tube videos fine on IE and Chrome but on Firefox all I get is a blank black box. The You Tube site opens OK, just won't play anything. I do not get a crash message about Flash. Everything was fine until a couple days ago. Version is Shockwave Flash Firefox5.0 installed
