To be perfect, it needs closed tabs historial.. Thanks !

This works exactly as promised.

However, I try to avoid crowding my toolbar with add-on icons. Instead of the icon, I'd rather that this would work via the right click context menu, or even better (much better) a keyboard shortcut.

dont work with android mobile. No button to find.
please fix... thx

Will be better if there have a context menu, like "Undo Close Tab" on AMO site.

I found this in Android Firefox add-ons, and while it installed perfectly, I see no button on the URL menu or any other way to get it work.
Either make it (PLEASE) function with Fennec (Firefox Mobile) Android version, or remove it from being listed among Firefox Android add-ons. I would prefer the former, I'd love to get this functionality without having to waste time on creating it myself - my project is kinda fork Fennec to use GUI that's mixture of old Fennec in Maemo Linux in Nokia N900 phone and modern desktop UI.

Works very well, easy to use, does its job. Nice work and thank you
