Расширение Chrome / FF / Safari: загрузка скрытой веб-страницы в режиме инкогнито.

var Cu = Components.utils;
Cu.import('resource://gre/modules/Services.jsm');
Cu.import('resource://gre/modules/devtools/Console.jsm');
var win = Services.appShell.hiddenDOMWindow
var iframe = win.document.createElementNS('http://www.w3.org/1999/xhtml', 'iframe');
iframe.addEventListener('DOMContentLoaded', function(e) {
    var win = e.originalTarget.defaultView;
    console.log('done loaded', e.document.location);
    if (win.frameElement && win.frameElement != iframe) {
            //its a frame in the in iframe that load
    }
}, false);

win.document.documentElement.appendChild(iframe);

должен сохранить глобальную ссылку на переменную iframe, которую мы добавили. то вы можете изменить местоположение iframe, как это, и когда он загружен, он запускает прослушиватель событий выше

iframe.contentWindow.location = 'http://www.bing.com/'

этот DOMContentLoaded идентифицирует все, что загружено в этот iframe. если на странице есть фреймы, он это тоже обнаруживает.

для удаления из истории в функцию DOMContentLoaded используйте службу истории, чтобы удалить win.location из истории: https://developer.mozilla.org/en-US/docs/Using_the_Places_history_service

Теперь, чтобы удалить файлы cookie из запросов на этой странице, используйте этот код:

const {classes: Cc, Constructor: CC, interfaces: Ci, utils: Cu, results: Cr, manager: Cm} = Components;
Cu.import('resource://gre/modules/Services.jsm');

var myTabToSpoofIn = Services.wm.getMostRecentBrowser('navigator:browser').gBrowser.tabContainer[0]; //will spoof in the first tab of your browser

            var goodies = loadContextGoodies(httpChannel)
            if (goodies) {
              if (goodies.contentWindow.top == iframe.contentWindow.top) {
                httpChannel.setRequestHeader('Cookie', '', false);
              } else {
                //this page load isnt in our iframe so ignore it
