jQuery UI Drag/Drop does not work in FF

I've been looking all over the place, but I haven't landed an answer yet. Is the current jQuery UI 1.8-1.8.2 supports Firefox 3+? I have 3.6.3 installed, but the example on thei开发者_高级运维r websites works for my IE7, IE8, Chrome, but not Firefox.

Is anyone else having this problem? It is not PC specific either because both of my PC at home and at work is having the same problem.

I removed my FF, removed my saved profile and reinstalled FF. Everything works now.
