title: HTML input placeholder text does not show in firefox
body: <p>I have the following input field</p>
  
  <pre><code>&lt;input type="text" id="search-box" placeholder="input the name" /&gt;
  </code></pre>
  
  <p>the placeholder text sets the default value of the field which is "input the name". If you click the field the text disappears so that you can type the name in the field.</p>
  
  <p>the placeholder text is shown in <strong>Chrome</strong> but not in <strong>Firefox</strong>, how to fix this firefox problem?? (I am using firefox 3.6)</p>
