Problems on this Forum login . ( FireFox browser ? )

Hello, i’ve just joined the community,

Yet, i have a problem when login this forum ,

  • on Firefox 52.6 ( Debian GNU / Linux OS )

i cannot enter… because of kind of unusable UI , leading to the fact of me not being able to enter username but password only ,

. This does not happens on (Chrome based) / Chromium / Iridium browser , from wich now i’m able to enter the Forum.

see attached secreenshot,
