I remember Firefox was biting me with this too at some time.  The 
solution for me was to go to Edit->Preferences, and in the "Security" 
tab uncheck the "Block reported attack sites" and "Block reported web 
forgeries" checkboxes.  The issue was that those features use sqlite to 
update internal databases of thousands of "malware" sites, and updates 
to these lists were bringing my CPU to its knees.

So try that and see if it helps.

Btw, if you're on a Core2 and a recent GCC, you might want to change 
that to "-march=core2" or "-march=native".
