Javascript issue in Firefox, not Chrome?
<p>The code below has two buttons - one of which copies a string of text to the users' clipboard (using Zclip), the other of which opens a URL in a new tab. The code below works perfectly in Chrome, but neither button does anything in Firefox. Any ideas as to why? I'm sure I'm doing something wrong and any help would be much appreciated!</p>

<pre><code>    &lt;dt&gt;
  &lt;div class="well"&gt;
    &lt;div class="buttoncont"&gt;
      &lt;button class="btn btn-success" id="copy-button26"&gt;&lt;i class="icon-plus icon-white"&gt;&lt;/i&gt;&lt;/button&gt;​
      &lt;button class="btn btn-success" onClick='funcName();'&gt;&lt;i class="icon-share-alt icon-white"&gt;&lt;/i&gt;&lt;/button&gt;​
    &lt;/div&gt;
  &lt;h4&gt;&lt;span class="name"&gt;Manage Users&lt;/span&gt;&lt;br /&gt;  &lt;span class="category"&gt;PORTAL&lt;/span&gt; &lt;span class="typeof"&gt;SETUP&lt;/span&gt;&lt;/h4&gt;
  &lt;span class="url"&gt;&lt;div id="itemurl26"&gt;https://manageusers.mysite.com/manageusers/showUsers?portalId=&lt;span id="psid"&gt;PORTALID&lt;/span&gt;&lt;/div&gt;&lt;/span&gt;
  &lt;/div&gt;
  &lt;script type="text/javascript"&gt;

  function funcName() {
    var myURL = 'https://manageusers.mysite.com/manageusers/showUsers?portalId='+portalid.value;
    window.open(myURL);
  };

    $(document).ready(function(){
      $("#copy-button26").zclip({
        path: "http://staging.mysite.com/hstoolkit/js/ZeroClipboard.swf",
        copy:function myfunction(){
          var theURL;
          theURL = 'https://manageusers.mysite.com/manageusers/showUsers?portalId='+portalid.value;
          return(theURL);
        }
     });
    });
  &lt;/script&gt;
&lt;/dt&gt;
</code></pre>
