Firefox 4 consumes more than 50% of CPU. I have seen a few questions already on this and restarting FF seems to fix it in some cases. Is there any feature in FF that can be turned on to see what exactly causes this CPU usage? It is annoying to start the PC fresh and have to see your PC act as if it was built using Intel 8086 chip and not Pentium Core 2.

Someone else will probably provide a better answer. I am not aware of such a debugging feature (monitoring CPU use) built into firefox.

If this occur in firefox safe mode there is a problem that needs investigating.

Do not forget to watch the number of instances of plugincontainer.exe that are open, there is a known bug causing problems with that see /questions/812618

Note also you are able to for instance turn off the hardware acceleration, or by setting a preference (html5.parser.enable;true/false) turn off the html5 browser ability of Firefox.

Presumably you have seen the Web Developer options from the firefox button. (And maybe considered firebug add-on, depending on what you are trying to check)
