Process Explorer shows me each tab I have open in Firefox but if one is using a lot of resources is it possible to know which one it is? Hovering the mouse/clicking properties doesn't seem to offer any info. Is there another way? If I kill that process in Process Explorer all the Firefox tabs crash.

Thank you. That was great. I can cross reference the PID to figure out what is going on.
