Here's the JsFiddle: http://jsfiddle.net/d6mmZ/7/
Clicking links 1 and 2 updates the text instantly. Clicking link 3 starts a slow fade-out. If I click link 1 or 2 during this time, the animation is supposed to be aborted and the new text shown instantly.
In Chrome, that's exactly what happens. In Firefox 13/14, there is a half second pause during which the content is completely invisible. If I let the fade complete, links 1 and 2 work instantly.
Is this a Firefox/jQuery bug or am I mis-using fade? If a bug, can I work around this somehow?
