I am consistently getting messages like this from my firewall. "firefox.exe attempted to establish a connection relying on an untrusted certificate to mozilla.cloudflare-dns.com. We blocked the connection to keep your data safe since untrusted certificates are issued by unrecognized Certificate Authorities."
