On nearly any site I visit, Flash and non-flash all have this issue, Firefox can use up to 90% of the CPU (2.26GHZ intel C2D) the ram stays quite low though, Chrome Safari and opera all operate at one tenth of this, or less.

Reproducible: Always

Steps to Reproduce:
1.Open firefox
2.Open activity monitor
3.Browse
Actual Results:  
High CPU utilization.

Expected Results:  
Low CPU utilization.
