Anyone notice this?

I'm in FF on FB and my browswer bar flickers

I'm in FF on Facebook and the upper left hand corner of the browser bar just flickers with
.. Facebook ¦ Home Mozilla Firefox to .......................Facebook ¦ Home Mozilla Firefox.

It seems like the page is trying to keep a live connection and refreshes in milliseconds. Any ideas what that might be?

Oh, and my cursor keeps going from the traditional arrow to the arrow w/ the hourglass.

How do they run that connection? Through and iframe?
