Hi, We have recently deployed a site on http2 (with ALPN support) using nginx. The site does not open in Firefox 47. The site supports following ciphers : _Protocols_ TLS 1.2 Yes TLS 1.1 Yes TLS 1.0 Yes SSL 3 No SSL 2 No _Cipher Suites (SSL 3+ suites in server-preferred order; deprecated and SSL 2 suites at the end)_ TLS\_ECDHE\_RSA\_WITH\_AES\_256\_GCM\_SHA384 (0xc030) ECDH secp256r1 (eq. 3072 bits RSA) FS 256 TLS\_ECDHE\_RSA\_WITH\_AES\_256\_CBC\_SHA384 (0xc028) ECDH secp256r1 (eq. 3072 bits RSA) FS 256 TLS\_ECDHE\_RSA\_WITH\_AES\_256\_CBC\_SHA (0xc014) ECDH secp256r1 (eq. 3072 bits RSA) FS 256 TLS\_RSA\_WITH\_AES\_256\_GCM\_SHA384 (0x9d) 256 TLS\_RSA\_WITH\_AES\_256\_CBC\_SHA256 (0x3d) 256 TLS\_RSA\_WITH\_AES\_256\_CBC\_SHA (0x35) 256 TLS\_RSA\_WITH\_CAMELLIA\_256\_CBC\_SHA (0x84) 256 TLS\_ECDHE\_RSA\_WITH\_AES\_128\_GCM\_SHA256 (0xc02f) ECDH secp256r1 (eq. 3072 bits RSA) FS 128 TLS\_ECDHE\_RSA\_WITH\_AES\_128\_CBC\_SHA256 (0xc027) ECDH secp256r1 (eq. 3072 bits RSA) FS 128 TLS\_ECDHE\_RSA\_WITH\_AES\_128\_CBC\_SHA ( 0xc013) ECDH secp256r1 (eq. 3072 bits RSA) FS 128 TLS\_RSA\_WITH\_AES\_128\_GCM\_SHA256 (0x9c) 128 TLS\_RSA\_WITH\_AES\_128\_CBC\_SHA256 ( 0x3c) 128 TLS\_RSA\_WITH\_AES\_128\_CBC\_SHA (0x2f) 128 TLS\_RSA\_WITH\_CAMELLIA\_128\_CBC\_SHA (0x41) 128 TLS\_ECDHE\_RSA\_WITH\_3DES\_EDE\_CBC\_SHA (0xc012) ECDH secp256r1 (eq. 3072 bits RSA) FS 112 TLS\_RSA\_WITH\_3DES\_EDE\_CBC\_SHA (0xa) 112 ---

You need to provide more information such as Firefox error messages, nginx config, server hostname, etc. You may find [Network Monitor — Firefox Source Docs documentation](https://developer.mozilla.org/en-US/docs/Tools/Network_Monitor) useful. I did notice your cipher suites include blacklisted ciphers, but this shouldn’t be an issue for outright failure.
