如何在不分析页面代码的情况下获取网站的收藏夹？

Question

I catch DOMContentLoaded event. I have document that triggered the event. In the most cases the favicon can be obtained so:

let favicon=gBrowser.selectedTab.image;

But if page is rather big user can has time to activate other tab. In this case this code will obtain favicon of the new tab. I can obtain tab neighter for document nor for browser. Is it possible to obtain favicon without analyzing page code? Thanks in advance

yep use PlacesUtils, just use the domain name of the page, you don't have to wait for page to load to get that. get it from document.location

var {interfaces: Ci, utils: Cu} = Components;
Cu.import("resource://gre/modules/PlacesUtils.jsm");
Cu.import("resource://gre/modules/Services.jsm");
var uri = Services.io.newURI('http://www.bing.com/', null, null);

var callback = function(uri, len, data, mimeType) {
      alert(uri.spec);
      console.log(uri.spec);
}





PlacesUtils.favicons.getFaviconDataForPage(gBrowser.currentURI, callback );
