very important productive extension. Thanks for save my tabs.

Its a life saver and with cloud sink, its also has life backups.

нет возможности из открытой сессии добавить вкладку в одну из сохранённых ранее сессий. Тогда был бы полноценный заменитель онлайн закладок, т.к. синхронизация с Google — наше всё :-).

Now that it supports cloud sync (the only thing it was missing), it's surely the best tab session manager out there, and I've tried many!
Thank you for your last update, hope you're going to support other cloud storage too as Dropbox and, why not, something open like Nextcloud.
Great work!

I love your extension but on latest firefox v76 it stopped working and lost all my sessions...doesnt shows me the open tabs so i cannot create manually either.....

Seems like IndexedDB was updated in Firefox v74. This addon stores sessions in IndexedDB. And old DB files don't work with new version. That's why we have errors like "IndexedDB error" or instantly closing Tab Session Manager window. Sessions are stored in Firefox Profiles foler. If you backup them and reinstall the addon it will start working fine. To recover them you need to install old version of Firefox somewhere, install Tab Session Manager, add backuped sessions to it (google for instructions by sienori on github) and export it to .sessions (JSON) format. Then you'll be able to import them to freshly installed Tab Session Manager in Firefox v74.
