Background

Firefox 2.0 introduces a built-in Session Restore feature, allowing the user to continue browsing from where they left off if browser restarts. Since this feature lends itself well to keeping track of data about tabs and windows, it’s also used for re-opening recently closed windows. This preference controlled how many closed windows are kept track of via the Session Restore service, but the ability to restore windows was never exposed in the UI.

Possible values and their effects
