title: Firefox cache textarea value?
body: <p>I found a strange issue. Open a simple page in Firefox, the code is simple as below:</p>
  
  <pre><code>&lt;html&gt;
    &lt;body&gt;
      &lt;textarea&gt;&lt;/textarea&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>In Firefox, I type some characters in the textarea. Then I click refresh button of the browser. Surprisingly, after the page refreshed, what I typed is still there in textarea. However, if I just focus on URL bar and press ENTER key, the textarea is clear after refreshing.</p>
  
  <p>I reproduced this in Firefox 3.6.12 in Linux and 3.6.3 in MacOS. And, I have only Firebug extension installed so it should NOT be due to Firefox extension.</p>
  
  <p>Is this a know issue?
  How to make textarea clear after Refresh button is clicked?</p>
