I love the Wikipedia animations -- they are usually extremely helpful -- but when I'm trying to read the article, I find them distracting. I usually move another window on top to obscure the animations so I can concentrate on the article. But there must be a better way. Is there a hotkey to stop animations? For Firefox in particular? EDIT: I don't want to stop animations permanently with about:config; I just want to pause and un-pause.
