DNSSEC

Check the DNSsec status of every website you browse.

DNSSEC Add-on for Firefox

Enhance your browsing security with the DNSSEC add-on, which verifies whether the domains you visit are signed with DNSSEC. This tool provides a visual indicator in your URL bar, making it easy to see if a site is secured against certain types of DNS attacks.

Defaulting to Cloudflare's 1.1.1.1 or Google Public DNS for queries, users should note that their browsing history may be transmitted for DNS resolution. The developer plans to support custom DNS over HTTPS services, prioritizing privacy for the most security-conscious users. Stay safe online with DNSSEC!

While cloudflare.com/ssl/encrypted-sni/#results tells me that "DNSSEC. Attackers cannot trick you into visiting a fake website by manipulating DNS responses for domains that are outside their control," this extension claims that "cloudflare.com not secure by DNSSEC. Domain www.cloudflare.com is not secure through DNSSEC. Your connection is prone to man-in-the-middle attacks."

Results inaccurate when choosing Cloudflare as the resolver, but can be worked around by choosing Google as the resolver. No option for custom resolver or even native recursive resolution.

Can hopefully be made even better with https://bugzilla.mozilla.org/show_bug.cgi?id=1852752
