On Firefox 92, 93, and 94, I am unable to visit http://egbert.net:80/ in an unsecured manner. [http://egbert.net:80/ http://egbert.net:80/] This website hosts BOTH secured AND unsecured HTML pages. I've already tried the following: - (hamburger)->Settings->Privacy&Security->Don’t enable HTTPS-Only Mode - dom.security.https_only_mode_send_http_background_request = false - network.dns.disablePrefetchFromHTTPS = false - network.dns.httpssvc.reset_exclustion_list = false - network.dns.upgrade_with_https_rr = false - network.dns.use_https_rr_as_altsvc = false - plugins.http_https_only = false - security.disallow_privileged_https_stylesheet_loads = false - security.disallow_privileged_https_subdocuments_loads = false - browser.urlbar.autoFill = false Wireshark is showing that Firefox is starting with port 443 right out the starting gate. What else do I have to do to turn off this port 443 for this website?
