</div>It also seems to move ECDHE handshakes to the top and only enables GCM modes for ECDHE, not for DHE. (Through specified in <a href="http://tools.ietf.org/html/rfc5288#page-2" target="_blank">http://tools.ietf.org/html/rfc5288#page-2</a> ) Which means, you only get AES_GCM with NIST ECC curves in reality.<br>
<br>
This is the order I get with RC4, DES, DSS, SSLv3 disabled in about:config.<br>
• TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256<br>
• TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256<br>
• TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA<br>
• TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA<br>
• TLS_DHE_RSA_WITH_AES_128_CBC_SHA<br>
• TLS_DHE_RSA_WITH_CAMELLIA_128_CBC_SHA<br>
• TLS_DHE_RSA_WITH_AES_256_CBC_SHA<br>
• TLS_DHE_RSA_WITH_CAMELLIA_256_CBC_SHA<br>
• TLS_RSA_WITH_AES_128_CBC_SHA<br>
• TLS_RSA_WITH_CAMELLIA_128_CBC_SHA<br>
• TLS_RSA_WITH_AES_256_CBC_SHA<br>
• TLS_RSA_WITH_CAMELLIA_256_CBC_SHA<br>
<br>
Anyone have an idea why Safari, Chrome, and now also Firefox prefer ECDSA?<br>
