title: Firefox problem: the state information is invalid for this page and might be corrupted
body: <p>Ive noticed that on my pages which uses updatePanel I get an error after ctrl+r or hitting F5. When I then try to do asynchronous postback there is the message:</p>
  
  <pre><code>the state information is invalid for this page and might be corrupted
  </code></pre>
  
  <p>I ve read that Response.Cache.SetNoStore(); but on my instance of ff 3 it doesnt really work.</p>
  
  <p>Is there any other solution ? I user ASP.Net 2.0</p>
  
  <p>thanks for any help</p>
