Strange. Firefox 2.0 doesn't appear to be much of a problem for me on my 
P4 2.4GHz machine. Then again I run NoScript and Adblock by default. 
Also, if you dig through the tabs in NoScript a bit, it has options to 
disable Flash stuff by default and then you can whitelist the Flash 
animation as well.

The only problem I have had with Firefox CPU-wise has been caused by 
annoying, poorly created blog sites (40+ some animated gifs in the 
background--ate up nearly all my available CPU resources).

Another thing, there were some known problems with Firefox 2.0.1 that 
were addressed with GTK filechoosers, if that's part of what you're doing.
