Extended DNSSEC Validator is a Firefox extension that allows you to check the existence and validity of DNSSEC signed DNS records for domains.
If a valid DNSSEC chain to the domain has been found, it checks for the existence of TLSA records that can store a copy of the hash of the HTTPS certificate. The results are shown in the address bar using the same scheme that Firefox already employs (identity box).
This allows owners of DNSSEC enabled domains to securely deploy self-signed certificates or provide additional trust in their CA-signed certificates.
