This is a great add-on that is very useful. It would be even better if it were compatible with Tree Style Tab, and restored not only the tabs themselves but their tree structure!

I would like to give five stars to this add-on as it's the best session manager but the interface is awfully becoming worse and worse:

- You no longer can select tabs nor windows to be opened. It looks like you can only remove tabs from the tree before opening a session, in which case you destroy the structure. Sessions lose the original structure and you cannot use them in the future as they were

- The maximum width of the side pane is 800 pixels, what does not leave room to access any of the valuable tools and options, such as rename a session, access the menu, see full tab description, add tags, open/delete a session

- You are somehow forced to configure the add-on to open the panel on a new tab which is inconvenient

The best FF session manager at the moment.
My wishlist:
- Could be a little faster at startup
- FF sync support would be great.
- Possibility to rename saved sessions

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.....
