Used to work perfectly for me, but for a while now when i open a session in a new window, all other firefox windows are closed automatically

Just 3* as only all tabs can be saved - should be able to save just SELECTED tabs. And many comments that import doesn't work, maybe because of diacritics or whatever.

Well this worked all of once for me... Click import session, it says it was imported, then loading session nothing is there

Przestało działać, nie można przywracać całych okien, tylko pojedyncze karty!

Import doesn't work

Love it, much better than many other clumsy "session sync/save" extensions. Unintrusive, lightweight... I'm proud of you sienori

Not a good tool if the sessions can't be downloaded - and not downloaded in .json but downloaded in CSV or HTML.

Deleted my session to spam save stupid autosaves when the session I had saved was saved manually, lost all my tabs forever, ridiculous do not recommend.

This is probably the most useful add-on I have. Being able to change between workflows with the click of a button is truly invaluable. I had a little trouble syncing my backup in the beginning but logged out and back in and it's worked great ever since.

Thanks for all your hard work creating it dev(s)!

Deletes saved session without warning.

Haven't tested yet, but finally found an extension that's almost replacement for the official Mozilla extension Session Manager, which didn't get a version for new extensions when legacy extension support was removed.

Only thing I'd love to have is the option to replace Firefox session restore with this so that when starting Firefox, it would open Tab Session Manager as popup - like Session Manager. You could there pick a session, AND unselect tabs if you wanted to leave some of them out. It also gave option to just start fresh, but of course you could load a session later. This is what I'd love to get when the browser starts, no loading previous session at startup but instead asking for one before opening browser windows (or maybe opening one empty browser window, then either loading selected session on that and new windows (if the session is multi-window).

Also LOVE that it supports Tree Style Tabs!!!
