I am day 1 using this add-on and I am super frustrated with the features not available on this one and was available on Firegesture but I am willing to give it a shot. This add-on does NOT have the feature to open links simultaneously with [Ctrl] + [Drawing gesture lines over links] which was super convenient when you are doing web research looking for relevant information. Would love to have it on this add-on. I may find more stuff that FIregesture had and Gesturefy don't.

----------
An year later of using this add-on, I still don't like it but just better than nothing.
Locker Gesture is glitchy, attempts to switch tabs sometimes forced back to the original tab or skips tabs and pops up context menu sometimes.
Just can't get the right tweaks of reaction times and sensitivities of gestures.
The behavior overall is just inconsistent and glitchy.
I am just using this because this is the better one among the worst ones.
MISSING FIREGESTURE!!!!!!!!!!!!
