Does exactly as it claims. : )

please add merge, skip duplicate tab, update/add with this session, edit

То что нужно лучшего и не сыскать. Хорошо что можно писать на GitHub пожелания, разраб потихоньку что-то допиливает❗
Респект❗

It's great but the syncing needs have an option to be automatic in some way(s). Windows killed itself and I hadn't synced it in quite some time so I lost my sessions. That's on me, not blaming the extension.

The best OneTab alternative. It's even better.

Best session manager ever because it handles tree-style tabs from Sidebery... but currently a few issues exist and the auto-backup and cloud backup stopped working.

I noticed that it does not save the history of the tab. i.e., forward-backward transitions in one tab. This is also important. not only restore windows and tabs, but also the history of tabs, position in front to back. tab chronology. not just a tab with one page, but with a list of transitions. this is super important! do it?

Долго искала решение задачи по восстановлению утерянной сессии. Найденное дополнение отлично справилось! Благодарю разработчика! Рекомендую оптимизировать поисковую информацию - дополнение трудно найти!

I would give higher but to me only having Google cloud as the only cloud backup solution is not a good option as We All Know what Google will do with your data

Great add-on!! I tried many before I settled on this. It has an intuitive UI, loads of features, and is really simple to use.

Some more features I would like are:
1) It would be more useful to save the tab-wise page history so that on restoring a session, I can move back and forth in history (granted, this may not work properly all the time due to caching, etc., but I still think access to a simple history would be very helpful).
2) It would be awesome if it were also supported on Firefox for Android.

Why on earth does this addon suddenly need to know my google email when I sync to GDrive? I find that quite suspicious and unnecessary? It worked fine before without those permissions. I really, really liked this addon. But now, not so much
