Works perfectly but only if you daily use function "Open tabs from previous session". I use, so it`s good for me. Thanks!

this is the great tools for my primary browsing experience,

simple but functional, big tanks for developer

This is the Function I like and use in Vivaldi, and needed here in Firefox.

Very nice and usefull, it reminds tabs after closing, and can manage it with the native mozilla groups, just add please shortcuts and correct a bug that sometimes idk why when closing it moves some tabs from one workspace to another.. , but before closing it works perfect
