Je viens de predre tous mes onglets : la liste de Tab session manager est vide...

Cette extension est bien... quand elle fonctionne. Puis quand on lui fait confiance depuis trop longtemps, on ne se méfie plus et elle nous trahit en supprimant tous nos onglets : plus de 80 onglets perdus ! Je suis anéanti :(

This is probably my favourite add-on. I organise my browsing using this rather than bookmarks (mostly).
The reason I haven't awarded 5-stars though is that I remember its predecessor, and the feature I really miss that that possessed was AUTOMATIC save to the SAME named session. (This would also reduce the vast propagation of sessions, at least for me)
I wonder if some unique identifier could be assigned to a session, and, if the user has chosen to "yes" a hypothetical "automatic overwrite/replace" setting, then, instead of saving to a new session it simply overwrites the old, therefore retaining the old name .... ?
I'd love to see such a feature added.

It would be great if it have save button with 3rd option "save current window WITHOUT hidden tabs".

The best session manager! Everything what's needed!

Regarding bugs and session db losses during FFox updates - this is FFox bug, not the addon's. The only cure is - make backups of sessions and addon settings (via export), also is good to switch to manual FFox update and backuping whole profile before update.

Hasn't worked on my laptop in over a year. Works fine on my desktop. Both machines have the exact same settings and apps. Only gave it the second star because it works on the desktop.

When I tried to add this extension to firefox I got the following response: Installation aborted because the add-on appears to be corrupt.

Great addon. One option I would like to see is possibility to be asked if previous session should be restored, like in good old Tab Mix Plus. Currently there is option to restore previous session on startup, without asking.

Works great! Would love the option to merge windows when restoring sessions =)

Unfortunately the latest version seems to be broken; it doesn't list saved sessions in the drop-down (though they do seem to be saved and can be seen in the JSON file if you export the saved sessions). 😕

This is a fairly good session-management extension for Firefox; it is pretty much the equivalent of the Chromium extension Session Buddy.

Till Now, I had no problems, but today, 13 July 2019, this extension seems to have some problems with syncronisation of SOME tabs. Indeed, some of my tabs cannot be loaded and I cannot see what was in these tabs since they are empty now. Please correct these bugs, maybe due to a Firefox update. Thanks in advance.

UPDATE, 15 July 2019 : PROBLEM SOLVED, THANKS !

Good extension but it's not totally a session manager since it does not save the history of each tabs.

Hi, I had an indexDB failure [after updating to FF 68], tried the Github 'Internal UUID copy-paste folder trick', didn't work; seems TSM's own json got corrupted, so I lost alll my sessions.
Please would you consider using eg Bookmarks [like MySessions] instead of indexDB that is so prone to corruptions?
Other than that, great addon, thanks.
