This affects only tabbed browsing. When opening more than 1 tab firefox.exe cpu increased to between 25-50% all the time. As soon as second tab is closed cpu returns to 0%. 

Reproducible: Always

Steps to Reproduce:
1.open firefox
2.open second tap
3.monitor cpu
Actual Results:  
excessive cpu memory used

Expected Results:  
excessive cpu memory used

This slows system down too much and stops me from using it even though i prefer it over ie7. ie7 does not have this problem even when >10 taps are opened.

It is very annoying.
Is this problem reproducible if you make a new test profile for firefox?
