title: Jquery attribute selector doesn't work under Firefox
body: <pre><code>$("div[f3id='vscroller'").each(function () {
  .... any code ....
  });
  </code></pre>
  
  <p>generates the following error message under Firefox.</p>
  
  <pre><code>Error: Syntax error, unrecognized expression: div[f3id='vscroller'
  </code></pre>
  
  <p>Change the code to</p>
  
  <pre><code>$('div[f3id="vscroller"')
  </code></pre>
  
  <p>doesn't solve the problem.</p>
  
  <p>Under Chrome it works fine.</p>
  
  <p>I would be thankful for any idea or work-around.</p>
