The functions of this addon are great, but what does not work at all is that the addon uses the entire memory.
and that is unacceptable!

When reinstalling, all sessions, despite the synchronization, are deleted. Thank you

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.
