I have noticed that when I stream video on both Vimeo.com and YouTube as well as other sites, the framerate is greatly reduced compared to when I stream video using Safari. I know it's not a hardware issue with my computer. Is there some problem with a plugin in Firefox. I enjoy Firefox because it's the fastest browser I have, I like the design, and it's very easy to customize. But I use Safari more often because of the video stream is very choppy. How could I possibly resolve this issue?
