do what it should , had never any problems ,perfect

Excellent. A must have.

Essential for all users. How this is not integrated as a standard function in Firefox is beyond me.

For those of you who don't know, pressing Ctrl + Shift + T on Windows and pressing Cmd + Shift + T on Macs can reopen the last tab you closed. And if you need to view all the tabs you've closed/searched in the past, you have your search history ¯\_(ツ)_/¯

(But if you're lazy, this extension is still pretty neat)

I have used this add on for a few years now. it has become an invaluable tool in my productivity. So many times I close a tab only to want to go back. This is the quickest way to do it. Many thanks to the developer.

... lo máximo, por error siempre cierro alguno pestaña!

Najlepszy!

Botón muy útil para recuperar la ultima o ultimas pestañas cerradas, deberia tenerlo por defecto cualquier Firefox.

Finally something that prevents school work lost lol
