If the menu bar is hidden then press F10 or hold down the Alt key, that should make the "Menu Bar" appear

• Make sure that the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"
• If items are missing then open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout"
• If a missing item is in the toolbar palette then drag it back from the Customize window on the toolbar
• If you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up.
