There are some banner ads that make use of animation.  These animations 
consume CPU resources.  When the ad is not displayed, such as when the window 
is minimized or blocked from view, the CPU usage remains the same.

Reproducible: Always

Steps to Reproduce:
1.Go to a website with an animated graphic
2.Minimize window
3.Watch CPU utilization

Actual Results:  
CPU utilization remains heavy

Expected Results:  
Mozilla should free the CPU resource when it is not needed.

We have many bugs related to CPU utilization of animated GIFs in general - some
of them also mention this problem besides the original problem, but bug #120154
seems to only deal with the CPU utilization during minimized / "in other tab"-stuff.

=> resolving "duplicate"
