Seems very similar to mine: http://www.userscripts.org/scripts/show/1927 , except you use the new, preferred GM syntax (good) and the "&&" shortcut for "if" (bleh).

I like to combine it with an "add to delicious" bookmarklet; YMMV.

"Your JavaScript can’t call printfire until Greasemonkey has added the function. (Which I believe is after the page has completely loaded.)"

Then, maybe, Greasemonkey isn't the ideal solution?

I do like your idea of using FireBug's logging more extensively, though.

Great idea. Any chance you can add it to the wishlist page?

Thanks MNU!

Oh my ... this is the first User Script that made me laugh out loud. Great job, and great taste!
