menu

Summary

Returns a reference to the NativeWindow.menu 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 NativeWindow.menu.add() and remove it using NativeWindow.menu.remove().

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

• from the startup() function, enumerate windows using nsIWindowMediator and add any menu items needed
• from the shutdown() function, enumerate windows using nsIWindowMediator and remove any menu items added

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.

Example

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

function showToast(window) {
  window.NativeWindow.toast.show("Showing you a toast", "short");
}
var menuID;
function addMenuItem(window) {
  menuID = window.NativeWindow.menu.add({
    name: "Show Toast",
    icon: null,
    callback: function(){
      showToast(window);
    }
  });
}

function removeMenuItem(window) {
  window.NativeWindow.menu.remove(menuID);
}
