I forgot I had this installed and it just saved my butt. For whatever reason, a Firefox window would not open after closing and restarting my PC. Tried a lot of things to get them back but then remembered this add on. Needless to say, I got my lost window back.

Too bad that the sole activity from the author in nearly a year is to update bakers.md. Not a single reply to the issues, and some of them are blocking issues, no commit on github whatsover.

all my saved, named and taged sessions have dissapeared! This program is usless unless I can easily recover what is lost.

Great addon! I love it! But, since a few weeks I got always this message, when I open the browser:

Simple Tab Groups addon conflicts with the following enabled extensions:

Enabled:
Tab Session Manager

To avoid losing tabs or their location in windows and groups, it is strongly recommended to turn off or remove enabled extensions that conflict with the Simple Tab Groups addon. You can do this on the addons settings page "about:addons" or by pressing the key combination Ctrl+Shift+A

???

Since Firefox removed the Session Manager I tried this extension as a replacement. It was nice to have a way to manage sessions but the memory usage is terrible. When I turned off this extension I went from using over 2GB of memory to 500 MB. This was despite limiting how many sessions to save so that it wouldn't consume too much memory. It's not great using Firefox and having it lag after keeping it open for a few days while using this extension.

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
