As far as I am concerned, there's an issue with Firefox's SecureDNS; i.e. DNS-over-HTTPS.
Remember I previously reset Firefox. Then Eset was detecting this web site OK. Today, I noticed that DNS-over-HTTPS was not enabled in Firefox, so I enabled it. When I subsequently accessed this phishing web site, Eset didn't alert. Then I disabled DNS-over-HTTPS and Eset alerted.
Also as far as Firefox's SecureDNS, weird things are going on. When I enable it and test on Cloudflare's test web site, https://www.cloudflare.com/ssl/encrypted-sni/ , strange things happen. First, it doesn't detect SecureDNS. Then on retest, it does detect it.
