Animated images
From MozillaZine Knowledge Base
Animated images are often annoying. You can turn them off in Mozilla Suite and Firefox, using the following procedure:
- In the Location Bar type about:config and hit Enter
- Type "anim" in the Filter field (to quickly find the needed preference)
- Double-click the image.animation_mode line and edit it to one of the following:
- none — will prevent image animation
- once — will let the image animate once
- normal — will allow it to play over and over
Alternatively, you can edit your user.js file to set this preference. For instance, to prevent image animation, insert the following into your user.js file:
user_pref("image.animation_mode", "none");
