If the author reads this, I can't view the site with the latest Firefox on Android (can't check the desktop one yet). The error is SSL_ERROR_NO_CYPHER_OVERLAP which means that the site and Firefox don't share any cipher so it's really the end of the story.The ciphers supported by Firefox areTLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 (0xc02b)
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (0xc02f)
