What is DNSSEC?

'DNSSEC' is a Firefox add-on designed to increase security during browsing by verifying the DNSSEC status of visited domains. It indicates whether these domains' zones are appropriately signed with DNSSEC. Although it leverages web services like Cloudflare’s 1.1.1.1 or Google Public DNS for DNS queries, transmitting your browsing history in the process, projections for a custom DNS over HTTPS service in the future promise enhanced privacy.

Summary

This add-on will display whether or not the visited domains' zones are signed with DNSSEC in your URL bar.

Please note, for the most privacy-inclined users, that it uses Cloudflare's 1.1.1.1 (by default) or Google Public DNS web services to perform DNS queries. So your browsing history will, in a way, be transmitted to Cloudflare or Google.

In the future, we will allow using a custom DNS over HTTPS service.
