The code updated to 0.2.0 0.2.1! - See the first post for details.

After digging through the
XUL Planet, I found new way to parse for HTML, which works great.
It's called something like createContextualFragment.
That makes it possible to detect the users that goes out or comes in.
And the new feature is it uses XMLHttpRequest to send the message also!
