The shift key does not work. Unable to use special characters within console but works when SSH is used.
This is a real problem with a PW containing special characters.
Your first reply prompted me to try another browser so I opened ProxMox in Edge and the shift key works in the console when connecting via Edge.
Shoot, really like Librewolf
Thanks for your help
You have to turn off the setting called resist finger printing. I ran into this myself, turning it off fixes it, and I'm able to use the built-in console. https://github.com/novnc/noVNC/issues/1882
