Why my Firefox always lack and why I have to wait for minutes to open a page?

Question

Dear customer support officer,
Why my Firefox always lack after I have update with Window 7 Service Pack 1? ... and why I have to wait for minutes to open a page?
I discovered from the "Task Manager", every time when Firefox is lack, it took up 100% of my "CPU Useage".
Below, kindly find my version spec for your investigation convenience. Many thanks in advance for your prompt support : )
Sincerely yours,
Charmayne
