Rated 4 out of 5 stars

I like this add-on, very useful to muzzle sites that get a little jittery by overdoing animated GIFs.

The Stop command on the page right-click menu is not reenabled, though, which means you don't get the benefit of this add-on on popup windows that do not have a navigation toolbar. I'd like to see this added to a future version.

This review is for a previous version of the add-on (1.3.0).
