Why wont Youtube videos load when using Firefox 3.6.3?


I've been having issues with youtube when using firefox, the video doesnt load or show up for that matter its just a black screen where the video should be and on the bottom left hand corner of Mozzilla it says "done" I've tried everything, I updated java and flash but nothing seems to work. What can I do? I know I can use other web browsers but I really want to fix this
