Rated 5 out of 5 stars
This is quite possibly my favorite Firefox add-on out of the hundreds I've reviewed. At the very least, it's up there with add-ons such as Tree Style Tab in terms of the great enhancement it brings to your organization and productivity while using Firefox.
Also, unlike other reviewers, I've had no trouble using multi-stroke gestures even on computers with low-end CPU and RAM specs. For example, I assigned "Reload" to the gesture "URD" (up-right-down) which can be triggered by literally drawing the shape (i.e. a square without a bottom) or, more simply, drawing an arc from right to left. The latter allows for a quick yet unique way to fire off "reload".
Excellent work, Gomita! I'm looking forward to future development of this add-on.
