Rated 2 out of 5 stars

Installed it because I was looking for click+wheel zooming. But in Ubuntu it only works if you hold down the wheel while turning it, which sometimes has the side effect of hiding all your toolbars. Hiding toolbars without offering an intuitive way to get them back = bad design. Had to uninstall.

This review is for a previous version of the add-on (0.4.3).
