Of the many tab managers I tested, Tab Session Manager is the one I love and use most. I has all the functionality I need implemented in a lean, efficent and no-frills way. Easy to understand, trivial to learn and has never failed me (using it about a year now).

It comes with built in manual sync to your own google drive account (no 3-rd party servers or sign-ups in between Firefox and your G-drive account).

It auto-backups all your Firefox windows & tabs automatically locally (time interval can be set in user settings) and is the best browser crash-insurance to date.

Tab Session Manager is a well designed, cross-browser and efficient FLOSS extension: Free (as in free beer), Libre (as in liberte, egalite, fraternite) and Open Source Software, with code access on github. It is well documented and in continuous feature development and bug maintenance (due to the ever evolving browser API changes).

My warm gratitude to the main developer @sienori on github.com

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

    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.

    Better than Firefox's built-in backup, but unnecessarily complicated!
    I don't see the point of many of the features. Unfortunately, there's no help section to clarify this.

    From the volume of open issues and the lack of activity on Git, It looks like Sienori has either abandoned this extension or doesn't have the time to maintain it. April 26.

    Auto-save doesn't work, hence data loss
