Fired when the browser stops displaying a menu: for example because the user clicked outside it or selected an item.

It is only triggered for menus that can be manipulated using themenus API itself: this includes the context menu, the browser's tools menu, and the bookmarks menu.

This is most likely to be used in combination with themenus.onShown andmenus.refresh() APIs: an extension can update the menu when it is shown, then undo the changes when it is hidden.

Firefox makes this event available via thecontextMenus namespace as well as themenus namespace.
