Nice one! Rated 5 out of 5 stars

I was thinking about exactly this yesterday, and today an extension comes out, thank you!

It saves a couple of clicks when using the mouse or pen; it's a natural feature for Linux users, but an improvement of the default behaviour of Firefox, that usually results in me pasting random text instead of scrolling.

Works fine out of the box.

This review is for a previous version of the add-on (0.1).
