Why does Firefox constantly use 50-60% of my processes in Task Manager when I am not active on line?

This is a frequent (2-3 times a day) occurrence when Firefox all of sudden is using processes even when I am not actually actively using websites? I may be just reading on a page and my task usage will be over 50%. Sometimes it will be just "firefox" and sometimes "plug-in for firefox".

See if you still have the issue in Safe Mode http://kb.mozillazine.org/Safe_Mode

Maybe you have too many addons or a corrupted profile.
