Every so often while I'm developing, Firefox will max out on CPU usage and I have no option but to quit it (sometimes I have to force quit).
Is there a plugin/extension that is like the Chrome process list that tells me what tab/addon of Firefox is using up so much CPU? Memory actually isn't a problem as I have upgraded to 4GB but obviously there's nothing I can do about CPU.
This is only happening on at work on a Mac with the 64bit version of Firefox 4.
