Works, even together with Tab Stash and Tab Containers. Just be careful about updating in macOS, I read that you might experience problems.

Desde que la descubrí hace 10 años (o más) no la dejo. La uso en varios navegadores y siempre tengo un respaldo en usb.

one of the best TAB extensions. It saves me a lot of trouble having a lot of opened tabs.

Keeps the open tabs closed :-) Thus saving a lot of memory, and my browser starts much faster
