About this extension

1. This Firefox add-on gets web site FQDN, domain name and IP when user browser to web site,
2. This Firefox add-on gets web site IP, PTR and CNAME form DoH server.
3. This Firefox add-on compares these data and changes icon color by result:
Green color = Nromal
Yellow color = Private IP
Red Color = Both IP form browser and DoH is different AND domain name is not appears in the PTR/CNAME

Developer comments

This add-on is sensitive to DNS GeoIP, so there will be false positives.
I am trying to solve the problem.
