All of a sudden I cannot watch any videos using Firefox. All I get is a square black box. I can see them if I use Safari. Why isn't my Firefox working? What can I do? Thanks.
try clear the cache your firefox
Try clearing the Cache in Firefox.
Tools-> Clear Recent History -> [v] Cache
or Firefox->Preferences->Advanced->Network -> Offline storage -> [Clear Now]
Try clearing the Youtube cookie in Firefox->Preferences->Privacy
If that still does not work then try making the youtube url as https://
It is apparently a issue with Youtube as people with other browsers are getting the same. http://www.google.com/support/forum/p/youtube/thread?hl=en&tid=3cda4dac122b8f13
Thank you very much. My videos are back this morning. Must've been a Firefox glitch yesterday.
Sure as hell ain't no Youtube problem when i can watch a video on Chrome or Safari.
I cleared the history and the Youtube cookies. Still won't work!
