Vrooming around with the mouse! Rated 5 out of 5 stars
Similar to my principle to reduce the strain of switching between the keyboard and mouse, this add-on reduces a lot of hunt-and-click by converting a lot of frequent jobs as gestures. All-in-one gestures helps me detach my mind from mundane tasks like going back or forward, switching tabs, closing tabs, opening closed tabs and even minimizing Firefox also!
Heck, I could even despise others for not using it.
