Steps to reproduce:
Animated gifs are frozen (paused on a single frame) if the following CSS properties are applied to the img tag:
position: fixed;
top: 50%;
left: 50%;
opacity: 0.6;
The animated gif will play if the position is changed to absolute or the opacity to changed to 1.
Actual results:
The animated gif is not animated when the window has focus. A single frame is displayed.
If you focus on another window and refocus on the window containing the animated gifs, the *paused* animated gif will be frozen on a different frame of the animation.

Expected results:
The animated gif should loop regularly.
Updated testcase to use an embedded datauri as the image src.

I see the same behavior in versions back to Firefox 4. The behavior is correct in 3.6.

This is an invalidation issue. The image changes if you switch away from the tab and then back to it.
