Attached is a testcase that shows high cpu usage for both firefox and mozilla.
It contains a few animated gifs. I resize my browser so the bottom part of the 
page, including the animated gif in it, is outside the window. There are still 
4 instances of the same gif visable.  CPU usage in this case is just a few %.

Now when I scroll the bottom part into view so that the 5th instance of the gif
becomes visible, cpu usage rises to 30% or 40%!

If other people can reproduce this I can file a bugzilla...
