title: Firefox strange single quotes conversion in urls
body: <p>Does anybody know why FF encodes single quote <code>'</code> into <code>%27</code> ?</p>
  
  <p>Single quote is supposed to be a valid char in URLs.
  In-fact all other browser IE7/IE8/Chrome5/Safari4 work well by NOT encoding single quote into %27.</p>
  
  <p>Is this a FF bug, or it's me that I'm missing something?</p>
  
  <p>I'm testing with FF3.6.1</p>
  
  <p>To easy test, simply add this in <code>yourpage.html</code></p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      window.alert("this url = " + window.location.href);
  &lt;/script&gt;
  </code></pre>
  
  <p>Then go to <code>yourpage.html?test=quote'encoded</code></p>
  
  <p>FF won't replace the url in the address bar, but it will display:</p>
  
  <pre><code>yourpage.html?test=quote%27encoded
  </code></pre>
  
  <p>All other browsers will display </p>
  
  <pre><code>yourpage.html?test=quote'encoded
  </code></pre>
  
  <p>Thanks!</p>
