I believe HTTPS Everywhere detects if a site sends a 301 or 302 redirect that conflicts with a rewrite rule, but it doesn't detect Javascript redirects like this page is doing: <script type='text/javascript'> if(window.location.protocol != 'http:') { location.href = location.href.replace("https://", "http://"); } </script>
