I've used this extension since its early days. I'd tried others, but this has evolved a better interface. I have one suggestion: when a conflicting (ambiguous) gesture is found (two equal gestures for different actions), the extension tries the older action first, then tries the next. That could be an actual feature: same gestures should be executed in the order they appear in the list (the gestures would have to be shown as an ordered list for that), maybe adding a "break" option to stop the execution at a certain gesture (e.g., a single gesture could trigger a Save Link and a Save Image, in that order, but if the image was a link, an option could prevent the image from being saved.)

Initially discovered this feature in Vivaldi and got hooked hard. When I switched to Firefox, it was only thanks to this extension, since I could keep using the gestures I got used to.

I even checked for alternatives and it seems this extension for Firefox is the best one. You can't seemingly do this consistently on Chrome (on Linux at least).

If you love the back swipe gesture on touchpads, this is basically the same but for a mouse (even faster imo). No need setting up very complex gestures. Just as simple back gesture alone makes this extension worth everything.

Personally I use the back gesture (swipe left with mouse right button) and close + restore tab mostly. Though you can add pretty much everything imaginable which I love!

Nice
