About Prospector: Snaporama
Today, we’re releasing an add-on called Snaporama. This add-on lets you instantly take a “snapshot” of all the tabs you have open, and later lets you open up a snapshot into a new tab group.
Prospector is a collection of experiments from Mozilla Labs focused on analyzing, experimenting and prototyping enhancements for how you search and discover content with Firefox. We’re focused on three main areas: websites you've visited, tabs you're currently viewing, and pages you haven’t visited yet.
