Rated 5 out of 5 stars

This is brilliant. I've seen other users' criticisms of SM's more complex functionality but I just wanted to save all my tabs in multiple windows, without having to do anything. Session Manager gives me more than I asked for - the option to restore closed tabs in many windows, restore sessions, save sessions individually and in groups, plus quite a bit of other stuff. It's very customisable. Love it!

This review is for a previous version of the add-on (0.7.2.1-signed).
