You have been subscribed to a public bug:

Jaunty running from a Live cd, nvidia proprietary driver and extra visual 
effects enabled.
On this page http://www.wdvl.com/Multimedia/Animation/GIF/Examples.html
the cpu usage is almost 100%, when in nvidia xserver settings, the opengl and 
antialiasing settings
are set to sync to vblank, allow flipping and 16x respectively.
Other combinations of high quality settings, also trigger the same problem.
Problem does not occur when .gif images are filtered with addblock or when 
nvidia xserver settings are set to default values.
Quantity of .gif images seems not to be relevant, same results in pages with 
less animations.
Same behavior exists in hardy normal installation, intrepid wubi installation.
This comment 
https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/125970/comments/78 in a 
similar bug points to a page, where the .gif image -not animated- if not 
filtered, creates the same problem in hardy. Intrepid and jaunty are not 
affected.
