Method summary

Attributes

Methods

activateApplication()

Activates the application, making it the frontmost application. The application should call this to activate itself when one of its dock menu items are selected, since doing so does not automatically activate the application.

void activateApplication(
  in boolean aIgnoreOtherApplications
);

Parameters

aIgnoreOtherApplications

If true, the application is activated regardless of the state of other applications. If false, the application is only activated if other applications are not currently active.

About dockMenu

By default Firefox adds two menu items to the dock menu. The menu items are "New Window" and "New Private Window". If permanent private browsing mode is enabled then the "New Private Window" menu item is hidden. This is created by using the dockMenu attribute of nsIMacDockSupport here: https://mxr.mozilla.org/mozilla-release/source/browser/base/content/browser.js#1562

This is seen here:

If you were to copy and follow that example you would replace the default native menu. This can be done like this:

var dockSupport = Cc['@mozilla.org/widget/macdocksupport;1'].getService(Ci.nsIMacDockSupport);
console.log('dockSupport:', dockSupport);

var win = Services.wm.getMostRecentWindow('navigator:browser');
var macMenu = win.document.createElementNS('https://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul', 'menupopup');
macMenu.setAttribute('id', 'myMacMenu');
var macMenuItem = win.document.createElementNS('https://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul', 'menuitem');
macMenuItem.setAttribute('label', 'Show Most Recent Window');
macMenuItem.setAttribute('id', 'myMacMenuItem');
macMenuItem.addEventListener('command', function(){
  var dockSupport = Cc['@mozilla.org/widget/macdocksupport;1'].getService(Ci.nsIMacDockSupport);
  dockSupport.activateApplication(true);
  Services.wm.getMostRecentWindow(null).focus()
})
macMenu.appendChild(macMenuItem);
var mainPopupSet = win.document.getElementById('mainPopupSet');
mainPopupSet.appendChild(macMenu);

let dockMenuElement = macMenu; //document.getElementById("menu_mac_dockmenu");66
let nativeMenu = Cc["@mozilla.org/widget/standalonenativemenu;1"].createInstance(Ci.nsIStandaloneNativeMenu);

console.log('dockMenuElement:', dockMenuElement);

nativeMenu.init(dockMenuElement);
dockSupport.dockMenu = nativeMenu;

This replaces the default menu with this one menuitem that says "Show Most Recent Window". Notice the activateApplication(true), if this is not done then Firefox will not be activated. The result of this code is shown below.

Notice how the "New Window" and "New Private Window" menuitem's are missing. Therefore, if you would like to add or remove items to the menu it is recommended to manipulate the default menu item which is on the hidden window of Firefox. Note: The hidden window of Firefox (Services.appShel.hiddenDOMWindow) loads on browser startup, so if you would like to access it on startup of the browser make sure to check and wait for the window to be loaded. This can be done by adding a event listenr for load of the hidden window.

This is the recommended way to add to the native menu, just maniuplate the default menu DOM element.

var macMenuItem = Services.appShell.hiddenDOMWindow.document.createElementNS('https://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul', 'menuitem');
macMenuItem.setAttribute('label', 'Show Most Recent Window');
macMenuItem.setAttribute('id', 'myMacMenuItem');
macMenuItem.addEventListener('command', function(){
  var dockSupport = Cc['@mozilla.org/widget/macdocksupport;1'].getService(Ci.nsIMacDockSupport);
  dockSupport.activateApplication(true);
  Services.wm.getMostRecentWindow(null).focus()
})
Services.appShell.hiddenDOMWindow.document.getElementById('menu_mac_dockmenu').appendChild(macMenuItem)

This adds the "Show Most Recent Window" menuitem from the previous example as a third item. Two types of elements:

• menu (if you would like to have sub menu items, make sure to set a label on the "menu" element)

• menuitem (like in example above)

Elements can be hidden by adding the hidden attribute to the menu or menuitem and setting it to true       .
