Fixes two missing extension from the HelloFirefox_120 parrot:

  • An empty session_ticket (35)
  • psk_key_exchange_modes (45) with psk_dhe_ke mode.

This is tested with Firefox 120 and Firefox 123.

Hi! Thanks for contributing to uTLS.

I went back and checked the current Firefox 120 parrot. Turns out I added it along when I first introduce GreaseECH Extension to uTLS. And it is not necessarily wrong, just less popular. I do see my Firefox browser still generates the same fingerprint (0040887d23cf42fc) under Private Browsing mode.

The parrot you submitted, with fingerprint 79562b48401fc449, is apparently more popular (9.2M vs 388K). So I am in full support that we should use the more popular one to replace the current one, which is much less popular.
