... to see WHICH pages are using the cpu? I want something analogous to ps.

When my fan turns on I want to see what the reason is. Normally I use ps (or top) for this, but when I have a dozen tabs open in firefox and I see that "Web Content" is using 100% of cpu this doesn't help me find out which tab is the culprit. I'd like something like ps or top for that Web Content process so I can kill that tab or disable some of its scripts. In fact it would be even better if the Web Content ps utility could tell me which scripts are using how much cpu.
