The video slows down and the audio gets out of sync. Top shows firefox using more then 120% of the cpu. Firefox menus become slow, scrolling is difficult, switching windows is painful. The problem bleeds to other applications and the GUI. Closing Firefox does not return things to normal, nor does simply restarting the OS. The system needs to be shutdown for 10 secounds or more for the problem to disappear.
