SO FAR SO GOOD! I just started using Save Tabs, so all I've done is save my tabs, close Firefox, then reopened it, and it restored my tabs. And it worked just as it said it would! That is a high complement, as most add-ons descriptions make the add-on sound easy and simple to use, but then you install it and it takes hours to figure out. I'm sure there's more this add-on does, and I will attempt to learn more, but to have it do the main function as easily as flipping a light switch is so very nice and such a relief!

Handy for restoring tabs that are accidentally closed and when restarting the browser. Pretty limited functionality tho overall.
