I need to administer my modem from an internal address. It uses HTTP:\\ not HTTPS:\\. No combination of settings for HTTPS-only allows me to hit the modem's page. I can ping the address. I've tried disabling HTTPS-Only without any change. I've tried keeping HTTPS-Only enabled and adding my modem's admin address to the exemption. I've made sure to restart FF after making the change. I've read this article: https://support.mozilla.org/en-US/kb/https-only-prefs#w_add-exceptions-for-http-websites-when-youre-in-https-only-mode. I do not have a padlock on the location address bar. I only see padlocks for HTTPS sites. I don't get the option to Continue to HTTP site. FireFox 108.0.2 (64-bit). Error: An error occurred during a connection to 192.168.X.X. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web. CenturyLink is unable to help me since I can't get the admin page.
