MDN will be in maintenance mode on Thursday September 21st, starting at 10 AM Pacific / 5 PM UTC, for about 1 hour.

Use the sessions API to list, and restore, tabs and windows that have been closed while the browser has been running.

The sessions.getRecentlyClosed() function returns an array of tabs.Tab and windows.Window objects, representing tabs and windows that have been closed since the browser was running, up to the maximum defined in sessions.MAX_SESSION_RESULTS.

You can then restore a window or tab using the sessions.restore() function. Restoring doesn't just reopen the tab: it also restores the tab's navigation history so the back/forward buttons will work.

To use the sessions API you must have the "sessions" API permission.
