in about:config, try setting browser.fixup.fallback-to-https to false.
I had to do this several versions ago IIRC. Only setting I can see in my config that might be related, I'm also on v120 and it's working fine for me to access all my local http-only services/devices.
Try to add :80 at the end of the link starting with http://
Check the network tab in developer mode just in case it is receiving a redirect from somewhere. I assume when you say "ipofdevice" that's an IPv4 address not IPv6. Has anything else used that IP address that might have set HSTS, or is the computer running Firefox sometimes on a VPN and there's another device using that IP on its non-vpn network
Yes, "ipofdevice" is an IPv4 address on the same subnet as the server that is using FF. No VPN involved and no other devices on that subnet that would have that IP.
Which setting in the network tab should I be looking for? I don't use developer mode very often.
