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 tabs. This preference controls how many closed tabs are kept track of via the Session Restore service.
