Title:
  The browser causes 20-40% CPU load when displaying an animated gif

Status in “firefox” package in Ubuntu:
  New

Bug description:
  When firefox is displaying a gif, for example
  http://i.imgur.com/MVKsc.gif , the CPU is under constant 20-40% load
  and system feels to run slower. Same load with and without any addons.
  When i remove the element which contains the gif via firebug, the load
  instantly drops to 1-2%.
