This extension saved my butt! I had to reboot my computer (forced to do so by Microsoft Windows update actually)... and when I opened Firefox, it didn't restore my tabs for some reason. This extension restored the previous session perfectly.

I used to love this add-on, have been using forever, but I don't think it's supported anymore. Synch with Google Drive no longer works, and issues aren't being addressed. It was a good run.

It was a good extension, now wtf has it become. HOW THE HELL DO I SAVE SESSIONS

La sauvegarde automatique ne fonctionne pas, les sauvegardes manuelles disparaissent, seule la dernière est visible, et disparait après réouverture de Firefox. Rien ne s'enregistre dans le dossier "TabSessionManager - Backup".
Dommage, l'ihm est propre et le principe de fonctionnement est bon.

Only saved 36 out of about 300 tabs in one portable profile. And does not load local web pages. though the URL is provided.

The functions of this addon are great, but what does not work at all is that the addon uses the entire memory.
and that is unacceptable!

When reinstalling, all sessions, despite the synchronization, are deleted. Thank you

Used to work perfectly for me, but for a while now when i open a session in a new window, all other firefox windows are closed automatically

Just 3* as only all tabs can be saved - should be able to save just SELECTED tabs. And many comments that import doesn't work, maybe because of diacritics or whatever.

Well this worked all of once for me... Click import session, it says it was imported, then loading session nothing is there

Przestało działać, nie można przywracać całych okien, tylko pojedyncze karty!

Import doesn't work

Love it, much better than many other clumsy "session sync/save" extensions. Unintrusive, lightweight... I'm proud of you sienori
