Title:
  Firefox html5 video performance

Status in firefox package in Ubuntu:
  Fix Released

Bug description:
  I have been experimenting with youtube videos on html5 technology and
  the same using flash player. I have noticed that html5 videos tend to
  be heavy on my processor with CPU usage shooting upto 70% on html5.
  With flash, however, the usage by fiefox + plugin-container isnt as
  much.

  Also another conclusive proof of more usage is that my computer
  (slightly old) heats up much more in a html5 video compared to a flash
  video.

  This bug is similar to
  https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/871412 , but
  different in the fact that I observe poor performance only in html5
  videos.

  (Is this issue perhaps because firefox fails to utilize my GPU, a
  nVidia 105M running nouveau driver, while flash does use it? Any how I
  can debug this and add to the report here?)

  Thanks
