Hi there,

I'm trying to disable insecure ciphers in TLS 1.2 since 1.3 isn't widely supported yet.

I'm using this to determine whats secure: https://browserleaks.com/ssl

I cant find any option to disable these two ciphers:

0x009c TLS_RSA_WITH_AES_128_GCM_SHA256 0x009d TLS_RSA_WITH_AES_256_GCM_SHA384

Thanks :)

You can disable/enable those ciphers in about:config:

security.ssl3.rsa_aes_128_gcm_sha256 for TLS_RSA_WITH_AES_128_GCM_SHA256 and security.ssl3.rsa_aes_256_gcm_sha384 for TLS_RSA_WITH_AES_256_GCM_SHA384

This will only work in the latest version of Firefox.

Hi Reuben:

I personally don't know how to do this, but I've asked some developers to help!

And hopefully I'll be able to report back soon!

Cheers!

Thanks for that Mike.

Is this in the Beta/Nightly?

I cant seem to find it in the Win 10 standard release 78.0.2 (64-bit) or Dev edition 79.0b7 (64-bit)

EDIT: ignore me added the value in about:config and toggled to False worked. Does not appear if searched. Cheers, Reuben
