Essential! Rated 4 out of 5 stars
Life quality improved! It's just super convenient doing quick and simple gestures to open this or do that, instead of having to carefully aiming my mouse at certain buttons and having to click. The rocker gestures often leave selection artifacts on the previous tab, and releasing the mouse outside of the page opens context menus, but other than that, it's pretty solid and customizable!This review is for a previous version of the add-on (220.127.116.11-signed).
