very useful for when you wanna shut the pc down but still save your tabs !
be aware tho to not save tabs for years tho , it's meant to be temporarily .

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

It finally happened... Multiple months worth of tabs instantly gone, the addon froze up and the extension menu for saving tabs wouldn't work, I close Firefox and then its completely empty. This extension hasn't been updated in a long time as well, I think it's time to find an alternative.

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

lost all my tabs...like years of tabs...and I just now realized there is no save file...just fucking url save files that you yourself have make in txt file format....yeeears of tabs and no way to get them back

好

onetab is a ticking time bomb bro, sooner or later you will lose all your tabs for absolutely no reason. gg.
