I'm running FF 3.6.6 on a MacBook Pro (new 2010) OS 10.6.4 and Firefox has been acting really slow and the death wheel comes up A LOT. I just re-installed snow leopard onto my MBP because flash was sluggish but just found out that it was FF all along. Whenever I go to right click or go to the menu, the death wheel comes on. When viewing flash videos, the video stops but audio continues for about 3sec then the video catches up. This happens every time. Is this just me or are there other people that are having the same experience? I'm not running anything else on the computer and it acts the same way. Any help? thanks and much appreciated.
