Works great. I have had any of the issues some of the guys are running into though.
Also, I've opened multiple browser windows, closing them or using a script to close the window doesn't cause the entire browser to try to close.
Running Firefox 4.0 on Vista Ultimate SP2
The only problem I'm seeing is the lack of a configurable keyboard shortcut that I can press to call Awesome Screenshot, I really don't want to have to use the mouse to just use it.
