Nice WebExtension - Works Great Rated 5 out of 5 stars

I like it a lot.
It offers some of the functionality of Tab Mix Plus that I was worried about losing such as Duplicate Tab and Undo Close. It's easy to customize gestures and add new ones, and another good thing about this add-on is that it'll still work when Firefox 57 is released.

Thanks for developing it.

This review is for a previous version of the add-on (1.0.2).
