Thanks for all the effort you've put into this! Though, in my opinion, some minor option is still missing. I think it'd be great if sessions (especially those saved manually) could be automatically uploaded into a cloud space, etc. so that they are synced. This way one wouldn't worry losing them either.

PS: Thanks for the fix. Just upgraded to 4 stars. Still waiting for the feature mentioned above to upgrade it to a 5-star.
Thanks again for the great job.

It would be great if it have save button with 3rd option "save current window WITHOUT hidden tabs".

The best session manager! Everything what's needed!

Regarding bugs and session db losses during FFox updates - this is FFox bug, not the addon's. The only cure is - make backups of sessions and addon settings (via export), also is good to switch to manual FFox update and backuping whole profile before update.

Great addon. One option I would like to see is possibility to be asked if previous session should be restored, like in good old Tab Mix Plus. Currently there is option to restore previous session on startup, without asking.

Works great! Would love the option to merge windows when restoring sessions =)

Till Now, I had no problems, but today, 13 July 2019, this extension seems to have some problems with syncronisation of SOME tabs. Indeed, some of my tabs cannot be loaded and I cannot see what was in these tabs since they are empty now. Please correct these bugs, maybe due to a Firefox update. Thanks in advance.

UPDATE, 15 July 2019 : PROBLEM SOLVED, THANKS !

Hi, I had an indexDB failure [after updating to FF 68], tried the Github 'Internal UUID copy-paste folder trick', didn't work; seems TSM's own json got corrupted, so I lost alll my sessions.
Please would you consider using eg Bookmarks [like MySessions] instead of indexDB that is so prone to corruptions?
Other than that, great addon, thanks.

Dobry dodatek. Brakuje tylko jakiejś synchronizacji między komputerami. Wtedy niewątpliwie 5.
