Does this work when Chrome is locked up? Usually people go to Task Manager because it's unresponsive.

It works when 1..n of your tabs are frozen, but the UI is still responsive e.g. you are still able to switch to other tabs. If your chrome is completely frozen i.e. you can't even open the chrome task manager, then you usually have to restart the browser.

Chrome does not "lock up", at-least on Windows without extensions. Individual tabs may crash or lock up, but the rest of the interface hasn't done that for a many years.

Nice!

I suspected gmail was the heaviest thing I regularly had open, but it's good to see the stats.
