Simple easy to use, and exactly what I was searching for, like the ability to chose the duplicate to close.

I recommend to use Ctrl + click on the add-on to not have your list opened at the very end ;)

some explanation would have been nice, for example what does "Promote mode" do? it seems to remove from the list and close that tab?

Anyway strongly recommended, for its simplicity and efficiency (I don't understand the negative review)

Does nothing on Android

Would have much preferred if this add-on behaved more like the built-in Firefox menu, which shows up to the right of the tabs as a "v" pull-down when there are too many tabs to display.
