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.

случайно нажала на значок и все мои 400 вкладок свернулись, нажала восстановить, а оно восстановило только 40 вкладок. пидарасы ебанные, верните вкладки. худшее приложение, ебаный врот. сдохните. верните мои вкладки твари.

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
