One tab is one of my favorite extensions. Lets me keep history of open tabs so I can go back to them, one click and all tabs are closed into one as a list. Reduces memory and if I want to I can go back and find the links and open them.
Its far more efficient then simple browsing history, since open tabs represent a more valuable window kept for later.
The extension is on chrome and firefox and is pretty popular, also very simple and open source. I really hope Brave adds it.
