try the safemode or an additional test profile:

 I already tryed in an alternate profile, and rigth now i am triyng safe-mode, but still running very lazzy. I have an impression that in safe mode it is sligthly faster, but still not even 10% the speed of my old 3.0 version. Also, the memory usage is very high, like 100 M. I wish the new alpha test version 3.1 gets the old speed.

Firefox 3.01 isn't slower for me at all on two win23 systems.

i also have experienced this problem.  i am running a 1.2 ghz celeron winxp sp3 computer with firefox 3.0.1.  i had no problems with firefox 2.  upgrading to 3 really slowed it down.  the cpu is hammered constantly when loading a page.  ping times are fine and using lynx results in pages loading quite quickly.  i am having to downgrade to firefox 2 just to be able to do any kind of browsing.
