Gogle chrome can help you. Turn on Developers tools (press F12) -> Profiles and in bottom line you find "Take heap snapshot" (eye icon).

Or you can start profiling and determine, which function eat most CPU resources.

Maybe firebug can help you, but I am not sure. Firebug can profile javascript, but I cant find **view heap** function. – neworld Nov 05 '11 at 07:56
I agree with @hguser: Firefox extensions often take a huge amount of CPU %. – Pete Wilson Nov 05 '11 at 08:07
I found the memory eaten in both IE7 and firefox. – hguser Nov 05 '11 at 08:16
