good

I love this Add-On, it saves every single window with one single click, the UI is clear and easy. My Mac Mini was in sleep mode tonight and when we had a power outage tonight, Tab Session Manager saved me and I could restore my complete session this morning

I have tried several other auto-tab openings extensions. This is by far the best and very powerful. The only thing I wish it did was allow you to drag and drop the order of how the tabs open. Regardless, it is a very professionally done extension. Thank you.

very useful addon.. it saved me several times when firefox lost my 3 windows with 1500 tabs each

esay to use, to manage, i recommand

Très pratique pour sauvegarder ses groupes d'onglets et reprendre une activité précise liée à ceux-ci. Il y a beaucoup d'options de sauvegarde pour choisir comment on utilise l'extension !

Very High CPU usage on many tabs.
Other wise is amazing tools i am using all the time. because of this issue i have to disable it and enable all the time to avoid my CPU fan go crazy.

Garbage extension. Can not find specific previous session. UI absolutely terrible. I can not emphasize how much I hate this PoS software. Uninstalling.

神です。ありがとうございます。無いと困ります。

Cloud sync is broken, infinite loading (Same thing like GitHub issue 1451). Suggested fix to delete all data does not work.

May work well for local-only use. But extension explicitly advertises cloud sync feature.

Do not use this on browsers with multiple workspaces like Floorp - it moves all the tabs to one workspace, rendering the extension worse than useless.

The addon is not bad, at first glance. He copes with the assigned tasks, BUT very frequent begging for money (donations) is very annoying. I even started writing down the dates when the internal "thank the author" timer went off.

And I was just opening a window to clear saved sessions.

Soliciting money all the time. Clunky. Sync tends to clutter everything because default settings haven't been thought through well enough. Does work pretty well, but if you're going to bug me for donations all the time, I'll just uninstall.

Can you add local support for the addon to remember spit view tabs? thanks

One of the best extensions I've installed. Simple, effective, and doesn't bloat the browser at all.
