I became tired that my firefox sucks at youtube video uploading.. so I switched back at Google Chrome..
I can listen now to my music, I can now scroll like firefox is.. and my browser doesn't slow down when I am watching a video in youtube HD.. yay!
I think I give Google Chrome a try now.. it is fixed from my earlier problems.. I deleted Firefox untill I really need it.
EDIT:
www.gamekings.tv doesn't load with Google Chrome.... time to use IE again.

EDIT 2: Mwah.. it does work.. but it does long to load it (It is a heavy flash site.. so no wonder)
