Just what it says Rated 5 out of 5 stars

It does exactly that, and does it quite well. Two things I'd like to see though, 1) A way to get the go-to-line functionality in there (maybe by adding a small menubar at the top of the page?), and 2) move the context menu item so it's next to the standard view source. Other than that, it's fabulous!

This review is for a previous version of the add-on (0.2).
