Help, all my sessions saved in the last 3 years have disappeared. I hope developer notices and helps me

Powerful. Vastly superior to bookmarkiof ng, best way to conserving extensive web research.

Facebook und X starten oft nicht im aktuellen Fenster, sondern machen eigene Fenster auf. Wenn ich vergesse, diese Fenster zu schließen, bevor ich Firefox beende, kann es passieren, dass beim nächsten Firefox-Start alle meine Tabs weg sind und stattdessen Facebook oder X startet. In solchen Situationen hat mir Tab Session Manager schon oft die Tabs wiederhergestellt.

one of th most important addons for FF!
thank you.
BEST: sync with cloud.

One of my most used extensions. I wish it was available for Firefox on Android.

Great!

Absolutely excellent. Has every feature I need and more, and I never use firefox without it.

Clean and powerful.

If you're losing your previous sessions or you want better tab management, then this extension is exactly for you.
