Doesn't work at all.

Excellent replacement for chrome's session buddy
Update: It is limited to 100 tabs and the new update made recovery from the backup impossible after it deleted all the sessions it had stored

Butifull fullwidth session manager...
BUT not saving previous/last sessions

Tab switching does not work. Session limit of 100 only. Should be no limit ever. Reminds me of the great Session Buddy.

It's not a bad extension. But it has serious issues. For example, I found a very severe extension breaking bug, but the only way to report this is to open a discussion in some Google group. No, I don't join Google, just to report a bug in an extension.

Secondly, it's not open source! Why?
If it were on Github, I already would've written a bug review and could've tracked myself how the progress on it is. Since this extension is not open source I can't do anything and I have a bad user experience.

Thirdly, due to above reasons, sometimes the extension does not work at all, because of the huge bug I found and I don't even know if it will ever be fixed, because the author does not let me report it on Github, where this project's source should be freely available.

Thanks!
This is the ADD-ONS I have always wanted in Firefox. There is a separate page to view the saved session. I hope to add the function with the default name of date+time

Excellent addon to save sessions.... except the CREATE button needs to be at the top of the window rather than the bottom... thanks :-)
