Disabling "blinking avatars" in Firefox

Can anybody tell me what the correct term is for the "blinking avatars" that folks often use in forums? I could post an example thread from a Tweaktown forum, but I hope this is enough to describe what I mean.

What I'm trying to do is to disable the refresh / display of those types of images; the constant blinking drives me absolutely mad making it impossible to view some threads.

I've searched FF add-ons for something that might do this, but the only ones I've seen are to disable all image display which is not what I want, but perhaps there is a specific search term that might reveal a better solution.

 

Do you mean animated GIFs? If so, you can change "image.animation_mode" setting: http://kb.mozillazine.org/Firefox_:_Tips_:_Animated_Images

 

Thank you! that's it. You are forever in my now-calm thoughts.

 

Does this work for animated avatars? I can bear animated smilies/emoticons but animated avatars drive me nutz.

 

Yes, that setting affects all GIF images.

 

...but, but, when I bought my avatar they told me was supposed to have chilling effect !
