When I go to Youtube, certain videos will not play now. This only happened after I downloaded firefox 4. I tested all of the plugins like the troubleshooting page recommended, but still nothing. Any help would be nice. Thanks.

If I try to play a certain person's vevo videos for example they won't play. Other videos posted by people will play, but it seems like if it is an official page by whoever (Lady Gaga, Justin Bieber, etc) they won't play and I have no idea why.

It seems to be any videos that have an ad that play before them won't start. I'm thinking it may be an issue related to Flash.

Updating Shockwave does not seem to help either.
