The file upload button http://mdbootstrap.com/components/forms/ doesn't work in firefox.When clicking the button, nothing happens. It works partially on google chrome, only when you click on the label text. <form action="#"> <div class="file-field input-field"> <button type="button" class="btn btn-default waves-effect waves-light"> <span>File</span> <input type="file" /> </button> </div> </form>
