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 NativeWindow.toast object, which can be used to display toast notifications on Firefox for Android.

A toast notification is a message that appears on the screen for a set interval and then fades away. It does not accept user input.

You can display a toast using, supplying:

  • the message to display
  • a duration parameter that controls how long the toast should be displayed. This takes one of two values: short or long.


In the example below, an add-on adds a menu item that displays a toast:NativeWindow-toast.png

function showToast(window) {"Showing you a toast", "short");  
var menuID;  
function addMenuItem(window) {  
  menuID ="Show Toast", null, function(){  
function removeMenuItem(window) {;  


Show a toast notification.
