Firefox 145 release is planned for November 11th, let's drop (Beta) to save an edit later:

Suggested change
- On Android, use Firefox 145+ (Beta)
- On Android, use Firefox 145+

Or maybe we can simplify this whole thing to:

- Default for [Firefox 132+](https://www.mozilla.org/firefox/) (Desktop) and Firefox 145+ (Android)
    - For QUIC/HTTP3, use Firefox 135+ (Desktop)

Or maybe start with Firefox 135+ and clarify that Firefox 132-134 only supports it for TLS and non QUIC/HTTP3.

Reviewer note: I can confirm that v22.20.0 (node:22.20) indeed supports X25519MLKEM768, and that v22.19.0 (node:22.19) does not. Both are LTS versions, 23.x is EOL and does not support it.
