Don't know if you know this trick, but it's handy after trying everything under the sun, open a terminal window and type:
Code:
kill `pidof mozilla-firefox`
It's amazingly useful when trying to kill multithreaded apps. Try it with any app by name as long as you put pidof in front of it. I almost never have to look up the process id just to find the app that I want to kill.
