The coroutine is a very simple www.

WWW www = new WWW("http://api.parse.com/1/login?username=" + username + "&password=" + pass);
        while (!www.isDone)
            yield return www;

        Debug.Log(www.text);

It works fine on chrome, but on firefox it doesn’t and I have no idea why because the logs makes no sense to me.

Are you still experiencing this problem ? If so, have you tried with the latest Unity 5.2.2 ?
