I just recently registered on this forum to see if I could help with answering questions from the users here. I did this because I like the apps and aims of Mozilla, and I'm willing to spend time helping people out with using these apps if I'm able to. That being said, questions worded like the one above do not make me want to spend much time being all that helpful. My suggestion is that you wait a few hours (or day or so) before posting about a problem that is causing some negative emotional response for you. If anyone has the same problem as what is described above, please post more information about their software versions (i.e. flash version), and whether or not the issue remains when taking the flash plugin out of the equation and using HTML5 on youtube (http://www.youtube.com/html5). My initial thought is that the issue is with the flash plugin being used. Has another flash version been used?
