The NativeWindow object is only available to privileged code running on Firefox for Android, and is intended for use by Firefox for Android add-ons.


Returns a reference to the object, which can be used to add items to the main Firefox for Android menu, and subsequently remove them. You can add a menu item to a browser window using and remove it using

A common pattern is for a restartless add-on to add and remove menu items in the add-on's bootstrap.js:

This ensures that the item is always present while the add-on is installed and enabled, and that it is cleaned up properly when the add-on is uninstalled or disabled. But note that bootstrap.js is not attached to a DOM window, so you need to get a window, for example using nsIWindowMediator, before you can use this pattern.


The following example adds a menu item with the label "Show Toast", which displays a toast notification when clicked:NativeWindow-menu.png

function showToast(window) {"Showing you a toast", "short");

var menuID;

function addMenuItem(window) {
  menuID ={
    name: "Show Toast",
    icon: null,
    callback: function(){

function removeMenuItem(window) {;


Add an item to the menu.
