Best add-on ever. The very first I install. Kudos. One small, but significant future request: Could you add a command to list history of the present tab? Pretty much as '[Popup] Recently closed tabs' do it.
Unfortunately this is not possible because Firefox does not provide an API for this. There is already a ticket on Bugzilla for this. https://bugzilla.mozilla.org/show_bug.cgi?id=1378651
I noticed that when using the right mouse button as the activation button, the right click context menu would immediately pop up, which is annoying if you just wanted to perform a gesture. To fix this, go to about:config and toggle option "ui.context_menus.after_mouseup" to true.
