Excellent! Rated 5 out of 5 stars

I first wondered why I'd want to use this instead of the built-in grab utility in OSX (or any other general purpose screen grab utility)...

One answer: With a general purpose screen grab utility, you can only grab the visible part of the page. This extension can grab the entire page (even very, very long ones).

Well done!
