show function usinng jquery does not open the pop up in firefox
<p>The open function below takes a div element adds a class "showModal" and then shows the pop up.This code works fine in chrome and IE browser, but in firefox the pop up does not show up on page load. But when I add break point to the lines within the open function, the pop up shows in firefox. Does jquery show function have some known issue in firefox</p>

<pre><code> Plugin.prototype = {

    open: function(element) {
            var $newEl = $(element).clone(true);
            var $contain = $mWrap.find('#SNIModal_Content').empty();
            $newEl = $newEl.appendTo($contain);
            $mWrap.addClass('showModal').show();
            return $newEl[0];
    }
    }; 
</code></pre>
