I have the following bookmark Javascript.
function bookmark(title, url) {
   if(document.all) { // ie
       window.external.AddFavorite(url, title);
   }
   else if(window.sidebar) { // firefox
      window.sidebar.addPanel(title, url, "");
  }
    else if(window.opera && window.print) { // opera
       var elem = document.createElement('a');
       elem.setAttribute('href',url);
       elem.setAttribute('title',title);
       elem.setAttribute('rel','sidebar');
       elem.click(); // this.title=document.title;
    }
}
AND HTML
<a href="javascript:bookmark('title of the page', 'http://www.domain.com');" class="bookmark" >
And the problem is that is working only in Internet Explorer. Is not working in firefox, opera, chrome. Also i heard that firefox have deprecated the function window.sidebar.addPanel, is there any way to fix all of this? PLEASE NO JQUERY.
