Rated 5 out of 5 stars

This has saved my bacon.

Does what it says on the tin - it saves the sessions (and your sanity) on those occasions that Firefox crashes. [When you leave the room for a few minutes to find M$ did a 'forced reboot'].

When you close a popup after the main window, you lose your tabs, unless you have session manager.

Even lets you go back a few sessions.

Great job. Really. Keep it up!!
