Not a perfect screenie. I tried to edit out the extra space... my second screen is set up off center. Meh, you can see the browser, though.
I am using the Firefox Logo persona as my current skin of Firefox. My toolbars are pretty customized with almost everything placed on the bookmark toolbar. I have the sidebar open to my extensions, but I have it set to its current minimum width (I can pull it all the way across the screen if I wanted to). I am using WindowBlinds with Prototype right now.
