title: "dojo is not defined" - Firefox 3.5 issue?
body: <p>Please take a look at this code:
  <a href="http://3wcloud-com-provisioning-qa.appspot.com/testAjaxDojo" rel="nofollow noreferrer">http://3wcloud-com-provisioning-qa.appspot.com/testAjaxDojo</a>
  Just tab off the "domain" input field to try to make the Ajax run. 
  (Note: the test Ajax web service always sends back the same message, it pretends to check if domain is available but it really doesn't). </p>
  
  <p>When running in Firefox 3.5, I get "dojo not defined" on the dojo.xhrGet statement. 
  It works fine in IE7 and Chrome browsers, and one friend tested on Firefox 3.0 and it worked. </p>
  
  <p>1) Is there something wrong with Firefox 3.5 not properly getting the dojo javascript from the CDN?  Possibly a caching issue? </p>
  
  <p>2) Do you Dojo gurus know of this problem?  Is it something that has already been reported to Firefox?  </p>
  
  <p>Thanks,
  Neal Walters</p>
  
  <p>Update: 9/1/ afternoon - I have uninstalled and re-installed Firefox 3.5.2 (but I kept my profile settings), and got same problem.  I'm on Windows Vista Ultimate. </p>
