I usually have a LOT of tabs open at once across multiple virtual desktops.  Once in a while I end up on a page that has some sort of advertisement (most likely flash) that makes my processor go absolutely nuts; it spikes up to 100% and just stays there.  Finding that tab to close it and get my computer back to normal is a pain!

It would be really great to somehow get a dialog listing all the tabs and the relative amount of work each is doing.  That way I can close that one tab quickly and without having to experiment by closing tabs that i'm not quite done with.


Reproducible: Sometimes

Steps to Reproduce:
1. Open many tabs
2. End up on a page that has some processor intensive task on it
3. Lose the tab among your sea of open tabs
4. Watch your CPU spike and then try to figure out what tab is the culprit.
5. Learn that trying to get FF to behave was a good way to clean up your open tabs.  ;)
Actual Results:  
Frustrating to find processor intensive tab; end up having to close a lot of useful tabs in order to find the misbehaving one.

Expected Results:  
It would be great to have a global view of all tabs and how much work they are doing to close it out.

Probably not technically possible, but I'll let someone else more knowledgeable than I close as WONTFIX if that's the case; confirming feature request.
