Gesturify 2.x does not work with Tor Browser 8
As reported on our blog Tor Browser 8 seems to break the Gesturify extension (see: https://blog.torproject.org/comment/277145#comment-277145):
Add-on installs and configures just fine, but the mouse gestures do not work. No matter which mouse gesture I try, there's always a diagonal line (starting from the upper left corner to the center of the browser window) and then nothing happens.
