I have the same problem on my Debian workstation running Jessie at work. While it's a fairly beefy desktop with a Core i7 and 16GB, it also has an ATI video card. I experience the same sluggish behavior watching YouTube videos through Firefox. Watching the same videos at the same resolution through Chrome does not produce the same sluggishness. I have not yet tried Chromium. While watching videos in both browsers I've viewed CPU usage in top. Firefox was chewing away over 50% of the CPU whereas Chrome consumed 11%. Additionally, I have a laptop and desktop at home running Wheezy and Jessie, respectively. Neither one uses ATI for graphics and I have no problems with sluggishness on watching YouTube videos with Firefox. You could try updating the driver to see if that improves performance. Otherwise, perhaps a different browser is needed. Hope that helps. -- Pete Orrall p...@cs1x.com www.peteorrall.com "If there isn't a way, I'll make one."
