Q: Movies are not working on the YouTube site. Why does it say I must enable JavaScript and Flash even if I already allowed youtube.com?
A: YouTube RECENTLY split its content across TWO domains, likely for performance reasons. Therefore you must allow both youtube.com and ytimg.com (you're probably missing the latter).

i have the same problem with mozilla firefox. first time it work fine and suddenly it stop working
