So wierd i just got this yesterday and it wont load the back of the page the header and everything only in firefox... I used Firebug and Javascript debugger and its still not fixed. Whats wierd is at first it was happening on a couple websites including youtube then i debugged and it fixed everything cept opggaming. Ive tryed reinstalling Firefox and im still getting error msg. I dont know much about this shit but any suggestions would be helpful. thanks
