Thomas,

Max/I are running a slightly later builds, 64.0a1 (2018-09-10) and 
(2018-09-12) respectively, and we're now seeing the 
psk_key_exchange_modes extension.

Can you confirm if you're seeing this (or not) with a more recent build 
of FF 64.0a1?

     "psk_key_exchange_modes (45)": {
       "ke_modes": [psk_dhe_ke]
     }

Thanks much,

Brad
