Yeah I noticed that video issue with FF2. I'm guessing it was an Adobe/Mozilla glitch.
It is probably caused by the swfobject script that all websites have to have nowadays thanks to the retards at Microsoft with their crappy IE7 for flash videos to be compatible on all browsers.
Also, on FF3 the new thread and post reply buttons just above the quick reply box are shifted to the left. I don't think this is a FF3 issue, just the coders of gfy fault .......
FF3 has improved it's CSS compability, so I doubt it would work backwords.

These bugs can be common due to IE's incompetent nature.
