Whenever I try to stream videos in the 720p or 1080p category (HD streaming) I get what I've termed as "frame hang" aka videos that are choppy when it comes to the frames being streamed at even rates. I've heard that a GPU Accelerated Flash Player add-on would solve my problems, and I'm willing to give it a shot. Only, I can't seem to find this add-on among Mozilla. Does a reputable and trustworthy add-on of this type exist?
