How do you run/activate other addon by using "Send message to other add-on"?

In Github there are 3 example but none show how to just run addon.

Simply amazing. Just a small flaw: would it be possible to have a command to find text on the page (Ctrl+F)?

pretty good，very convient！

отличное расширение, быстро привыкаешь

以前竟然不知道有這麼好用的東西，真是太感謝作者了

I've used this extension since its early days. I'd tried others, but this has evolved a better interface and is, by far, the most powerful, allowing stacking commands in a single gesture (if one fails, it goes to the next in the stack.) It also allows interaction with other extensions (which I'm still trying to figure out...)

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!
