Hello everyone,

I am using Firefox latest release (eg 145.0.1).

At https://developers.cloudflare.com/ssl/post-quantum-cryptography/pqc-support/ , it seems that X25519MLKEM768 is supported since Firefox 132. Do you confirm ?

I ask this question because when I am connecting to https://pq.cloudflareresearch.com/ and activate the network tab before reaching this URL, and looked at the security tab on the right bottom panel, as you can see in the screenshot attached, in the Exchange group keys, I see x25519 and not x25519mlkem768 meaning that Firefox is not PQC ready for key establishment :-(

Best Regards.

Hello,

I visit an other site and this time in the Exchange group keys I am able to see mlkem768x25519 So it means that Firefox 145.0.1, at least, supports PQC key exchange algorithm.

Best Regards.
