As I misused the bug id of Ed25519 for X25519, I put the info here by hand :\

Release Note Request (optional, but appreciated)
[Why is this notable]:
The Curve25519 algorithms are one of the most used in cryptography. It has a better speed than the NIST curves key exchange algorithms and Curve25519 does not have a governmental origin.
All the other browsers already support Curve25519 algorithms, so this work also improves the interoperability with the other browsers.

[Suggested wording]:
WebCryptoAPI is now supporting Curve25519 primitives (Ed25519 signatures and X25519 key generation).

FF130 MDN docs for this can be tracked in https://github.com/mdn/content/issues/35280. Work essentially done, though waiting on reviews.
