Bug Summary

The built-in Mouse Gestures are, I believe, based on Gesturefy, but there are a few missing options. Some seem quite hard to implement, like those in #1974. But one that I miss seems fairly trivial: "Focus previously selected tab".

(Not sure if this is a bug or a feature request, but I will post the PR in a minute anyways.)

Reproduction Steps

1. Open Mouse Gestures in about:hub
2. Try adding a new one/editing any
3. There is no Action option like "Focus Last Used Tab" or similar (only options that shift focus sequentially)

Expected Behavior

There should be an option that could be configured to jump to the last used tab. Just like a single press of Ctrl+Tab works when the "Ctrl+Tab cycles through tabs in recently used order" option is on:

Actual Behavior

There is no option that would focus the Last Used Tab.
