Facebook Javascript SDK Cookie

[unduthCum]

i wrote for my Node.js Applikation a model (backbone), that realizes the authentication with Facebook Javascript SDK.My modelcode is here:\[code\]define(['jquery','underscore','backbone'], function($,_,Backbone) { var facebookUserModel = Backbone.Model.extend({ initialize: function() { console.log('FacebbokUserModel initialized'); // bind statusChange to this context _.bindAll(this, 'statusChange'); // be notified when the session changes FB.Event.subscribe('auth.authResponseChange', this.statusChange); } //saves actual status ,_loginStatus : null //return true/false if user is logged in ,isLoggedIn : function() { return this._loginStatus === 'connected'; } //check whether user is logged in or not //used for firsttime invoke ,getLoginStatus : function() { _this = this; FB.getLoginStatus(function(response) { _this.statusChange(response); }); } //log user in ,login: function() { FB.login(function() {}); } //log user out ,logout: function() { FB.logout(); } //treat changes on status ,statusChange: function(response) { console.log('statuschange'); if(this._loginStatus === response.status) return false; var event; if(response.status === 'not_authorized') { event = 'fb:unauthorized'; }else if(response.status === 'connected') { event = 'fb:connected'; }else { event = 'fb:disconnected'; } console.log(event); // RESPONSE IS SHOWN CORRECTLY EVEN IN FIREFOX console.log(response); this._loginStatus = response.status; this.trigger(event, this, response); } ,sync: function(method, model, options) { if(method !== 'read') throw new Error('FacebookUser is a readonly model, cannot perform ' + method); var callback = function(response) { if(response.error) { options.error(response); } else { options.success(model, response, options); } return true; }; FB.api('/me', callback); }, });return facebookUserModel;});\[/code\]Initfunction\[code\]FB.init({ appId : 'myappId', // App ID channelUrl : 'channelurl', // Channel File status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true, // parse XFBML oauth : true});\[/code\]When i execute this code it is working fine in Chrome and in IE. On serverside i can validate this cookie really easy but i have a problem with Firefox. Firefox shows the response correctly(clientside) but it does not create an fbsr-cookie. Can somebody give me a hint why? How can i handle this problem?greets
