This takes the code from 
<a href="http://www.cs.cmu.edu/~perspectives/firefox.html">CMU Perspectives</a>
that removes the X.509 SSL Certificate nag screens in Firefox 3.0 and replaces
them with a simple javascript confirm dialog to allow the unsigned certificate
for the rest of the browser session.

<p>
<a href="x509-free.xpi">Drag this link to your address bar</a> and open with 
firefox.

<p>To view the code, save the xpi file and use your favorite unzip tool to 
open the archive.

<p>Updated 20100324 for Firefox versions greater than 3.0.
