XUL: window._content
It took me a while and a lot of asking on the IRC channel (#xul), but I finally found out how to get access to the current web site shown by the browser. I had to digg into some other extensions and I found it. I just wanted to manipulate the DOM of the currently shown web site a bit (nothing greasemonkey like, just tiny steps!).
window._content is your friend!

Just use window.content, the underscore version is deprecated.
