FF Rocker is a Firefox extension, a Rocker Gestures for Firefox. Rocker Gestures work by holding down one mouse button while clicking the other. (i.e. holding right then clicking left will go back, left then right goes forward).
Extremely streamlined, this addon adds functionality for the back/foward rocker gestures. While there are others that do the same, the author wanted one that only performs rocker functions and has error handling to alleviate some of the issues experienced in other gesture addons.

Requirements:
* Firefox
