Hi,

I was looking at the "Client Capabilities: Firefox 24.2.0 ESR / Win 7" at: https://www.ssllabs.com/ssltest/viewClient.html?name=Firefox&version=24.2.0%20ESR&platform=Win%207

 

There is listed "TLS_EMPTY_RENEGOTIATION_INFO_SCSV (0xff)" af the first place of Cipher Suites in order of preference. This looks strange to me. According to the web page: http://tools.ietf.org/html/rfc5746#section-3.3 this is even not a cipher. Why is this "cipher" listed?

Thanks
