cancel or abort gesture Rated 3 out of 5 stars

Not fair from me having to vote a star/s without testing it.
I am in a hurry (wouldn't write this comment yeah :0) if so) and I wanted to use my mouse gestures in a recent firefox installed in this pendrive with PA (portable apps - similar to the U3 application). I normally use fire gestures ext. and a "long time ago" in some previous Firefox version, I used some other mouse gestures extension I really don't know its name now. It's really a shame not to try this one since I read many good stuff from users of this one and I wanted to try it out (for now) but I can't seem to find out how to cancel the gesture after it started. In fire gestures I can even pick the time to wait for the abortion of the gesture.
Resuming: I'm a fire gestures user and gave a try at this one but since I don't find out how to cancel a gesture I'm disabling it and install FG. All I really use is fwd/back and cancel; and in settings: set color, width and time for cancel gesture.
I also use - mouse related - mouse zoom and double click to close tab. "Of course" I use other extensions as well.

Can some one tell if there is such option (to cancel gesture) and how to do it?

To the author: if there isn't that option could you add it in a future update please?
Thx and sorry for any "redundancy"(?) or being too repetitive
