Click Services tab.

NOTE. If you use different firewall, than Windows firewall, turn Windows firewall on, just for this test, since your regular firewall won't be running.
If you use Windows firewall, you're fine.

Open Firefox. Check CPU usage.

Close Firefox. Open Windows Explorer, navigate to C:\Windows\Prefetch, and delete Firefox prefetch file.
It'll look similar to this:
FIREFOX.EXE-E60C0AA7.pf
Take a note of a file size, and let me know how big it was.
Restart computer. Start FF, check CPU usage.

Restarted the computer.

Two more things to try...
1. Right-click on the Firefox icon you click to start Firefox, click Properties, click the Compatibility tab, make sure the check box under Compatibility mode is unchecked, and restart Firefox. Check CPU usage.

2. Uninstall Adobe Flash, using this: http://kb.adobe.com/...rnalId=tn_14157. Install fresh copy. Check CPU usage.
