Rated 2 out of 5 stars

Defects:
No Wheel Gesture supported.
No Rocker Gesture supported.
Besides, you can not create your own gestures.
Last but not least, you can't have both gesture tip and gesture trail at the same time.

Still there are a lot to learn from FireGestures.

This review is for a previous version of the add-on (1.1.1).
