Is smooth scrolling turned on in Firefox (I think it is on by default 
since 12.10)? It can consume a lot of CPU.  You can turn it off through 
Edit>Preferences>Advanced>(general tab) Uncheck 'use smooth scrolling'. 
You could try turning off hardware acceleration too if that is causing 
problems, though normally you'd want that left on.
