Doesn't work at all. This extension can't save any session. Also, GUI is buggy.

He's asking for money!!!

Since over a week there came two updates asking for Crypto money on the update page in the webbrowser that opens after an update and also the Backup feature get disabled. I don't think that comes from the original author and I'm worried the addon was hacked and is now used for Crypto scam. Deinstalled it and can only suggest others to do the same.

Lost my tabs and tried to load autosave made by this addon. It turned out that the data in this save was out of date by a year. For a whole year this addon made autosaves with the same data

"The save location is limited to the folder under browser download folder"
This is completely useless for syncing between computers - I cannot save to OneDrive folder.

Container support required

Sometimes it works, sometimes not. When its not working it can only opens one of the windows from the saved session.

it save to my bookmarks and bloats it up.

and saved sessions take forever to load.

effectively useless :(

Solo restaura las pestañas que hayas usado el dia que se guarda la sesion. NO restaura las pestañas abiertas que no hayas usado

I like the concept. Unfortunately, I found this add-on unresponsive to my settings; and when I had a crash that Firefox did not recover, this add-on did not help.

Edit: replying to the developer response: it appeared that nothing had been saved for the past several weeks. The add-on kept ignoring the folder that I designated for the backups; there aren't any recent backups in either my specified folder or in the folder that the add-on kept choosing. Possibly they are somewhere else. But I don't see them in Firefox Bookmarks either.

Unreliable. Several times from one day to the next the content of a saved sassion has changed with tabs missing

Doesn't save a session automatically. More over it creates blank tabs every time I restore the session.

Absolute Crap. More like a virus that will disable your web browser and refuse to allow you to delete the 'session' backups it creates. Stay well away and use any other Session Tool created by a competent developer.

This is a poor, sad and sorry replacement for the original Session Manager. Slow, resource-hungry, ugly.

All of the sessions I had saved disappeared into thin air without any kind of warning when firefox auto-updated. Back in Session Manager, all I had to do was import all my sessions from a folder it had automatically saved them to on my computer, which I was able to choose myself.

Am I missing something? Because AFAICT you either have to manually press the 'Save the session' button or set auto-save to 5 minutes (not recommended).

Didn't saved all tabs and when it was called to do it's job it return duplicated disordered tabs. A f'd up mess. Awful!!!
