title: InnerText alternative in mozilla
body: <p>Does any one know innerText alternative of a span in mozilla? 
  My span is </p>
  
  <pre><code>&lt;span id='cell1'&gt;&lt;/span&gt;  
  </code></pre>
  
  <p>and the javascript is </p>
  
  <pre><code>document.getElementById('cell1').innerText = 'Tenelol';
  </code></pre>
  
  <p>But Mozilla is not supporting this!!</p>
