Firefox just pegged my CPU at 100%...

I was browsing CD, and I was reading this thread:

and I noticed my fan turn on. That was really odd as that only happens when I am actually straining my computer. I've got a brand new Dell Latitude D520 laptop--that's a Centrino Duo 1.66ghz dual core. After looking in my system monitor program and the task manager, I noticed that my processor was pegged at 100% usage, and Firefox was using 96-99% processor time in Windows task manager. I closed it in desperation--this was freaking me out. It went away and left the processor idle again, and I am happily browsing like normal once again. I am wondering, have any of you Firefox users seen anything like this? A quick Google suggested that the Flash plugin might be causing this, but I didn't see any flash content on the page I had open.

At first I had suspected my anti-virus, but that's not what task manager said.

I'm confused. And there are no updates available from Mozilla, so they either haven't seen this problem or don't have a fix yet.

I hate it when I break stuff.

Just curious as to whether or not you've seen this type of behavior in FF. FF2 has given me other troubles, too--the "grey window of death" I call it, I will post a screenshot when it does it again. I just hope that things pull together and FF goes back to its seemingly bug-free self.

Attached are two pics, the first (start_CPU_peg.jpg) is what my system monitor recorded the processor usage at when the peg started. It looks like it pegged one core, then started another thread that pegged the other. The other pic is end_CPU_peg.jpg, when I closed FF about 30 seconds later and the processor usage went back to normal.
