Right mouse button (no) problem! But incompatibility with FireGestures and All-in-One Gesture. Rated 4 out of 5 stars
(Edited: No problem if you use "alone")
Edited: The problem was the conflict with FireGestures extension. Without is, was no problem at all. ...All-in-One Gesture's rocker navigation does not work with Scrollbar Anywhere 2012 :-) Even i set the Scrollbar Anywhere 2012 to the middle button!
