Is Firefox 4 making my Mac get really hot?

    I have a 2 year old Mac which is suddenly (and for the first time) getting very hot - enough to be uncomfortable on my lap.

    It's happened the last couple of days and I downloaded and started using FF4 a couple of days ago.

    I can't believe a web browser does it? Does it?

    Have a look at Activity Monitor (Applications / Utilities /) and select All Processes and sort by CPU to see what the culprit may be.

    ok. Before we go any further - how'd you get your GUI to look so cool??

    It is the normal GUI and Photoshop and Mac OS X' ability to properly screenshot elements of the UI.
