Date & Firefox

Hello,

Something strange happen, the date box display properly on chrome, but not on firefox ( I mean without calendar icon, or an option to write a date). You can check here my simple script that I'm writing to learn Laravel :

http://demo.beginfromhere.com/laravel/public/users

my blade part of this issue is here :

       <div class="form-group">
              {!! Form::label('published_at','Publish On:') !!}
              {!! Form::input('date','published_at', date('Y-m-d'), ['class'=>'form-control']) !!}
       </div>

Do you have a solution ?
