Forum scrolling issue

Hey guys, need some brainpower to figure something out here.

My computer works fast and smooth most of the time. I don't have any issues with any programs or other websites. HOWEVER, on THESE forums, when i use my scroll-wheel to navigate, it's very choppy and laggy. My system manager reports that almost 25% of my system resources are going towards Firefox when I try to use the scroll wheel on the forums. Looking at the usage graph, three procs remain unused while the fourth one goes ballistic trying to crunch all the data apparently required to scroll down a page length >_>

I should also note that if i don't go to Facebook first, this issue doesn't arise as often. In fact, sometimes closing my browser, letting it sit for a minute then restarting alleviates most of the lag.

So it seems to me there's some kind of Facebook/Firefox/CoH Forum incompatibility. here are my readouts from CoHHelper and HiJackThis logs:

What happens of you use another browser?

IEX, Chrome, Safari, Opera, etc?

Don't use 'em, couldn't tell ya =/

Though it would be in the best interest of a "scientific" study of the situation if i tried to use 'em. *SIGH*

I had this issue with Firefox on the Mac at my old job, I think it actually had to do with the mouse not being completely functional. Sometimes the scroll ball would work sometimes it wouldn't, more often than not it would scroll up but not down.

I reported a similar-sounding issue once a while back. It occurred intermittently every once in a while, but I don't know why. Haven't noticed it in a long time though.
