That depends on what do you consider as a weak cipher, I do have security.ssl3.rsa_des_ede3_sha set to false in Firefox as well. If you mean all ciphers that do

That depends on what do you consider as a weak cipher, I do have security.ssl3.rsa_des_ede3_sha set to false in Firefox as well. If you mean all ciphers that don't have forward secrecy then I guess it may broke a lot more. edit: i also have security.ssl3.rsa_aes_256_sha disabled, so my only non forward secrecy cipher fallback is TLS_RSA_WITH_AES_128_CBC_SHA
