Disable Blocking of Bonjour (.local) Websites

I am trying to connect to a .local website, and LibreWolf says it can't connect to server (one of the worst UX error pages I've seen). Google and DDG are of no help, and I do not want to resort to using another browser for something that should be simple to disable.

I have added my domain to `network.dns.localDomains` and that did not appear to work. I have "DNS over HTTPS" disabled completely. I do not know what else to try.

Please help.
