Opening a new browser window

To open a new browser window, you can simply use window.open. However, window.open returns a DOMWindow, not a ChromeWindow, so you can't get access to the browser chrome from it. You can, however use nsIWindowMediator to get the window you just opened.

Example

window.open();
var wm = Components.classes["@mozilla.org/appshell/window-mediator;1"]
    .getService(Components.interfaces.nsIWindowMediator);
var newWindow = wm.getMostRecentWindow("navigator:browser");
var b = newWindow.getBrowser();
