| ==Background==
| |
| Firefox 2.0 introduces a built-in [http://wiki.mozilla.org/Session_Restore 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 controls how many closed windows are kept track of via the Session Restore service.
| |
|
| |
| ==Possible values and their effects==
| |
| A positive integer indicating how many window closures to remember for later possible restoration. (Default is 10)
| |
|
| |
| ==Caveats==
| |
| * The [[browser.sessionstore.enabled|Session Restore service]] must be active for window data to be remembered.
