Comcast has become the first ISP to join Mozilla’s initiative and “provide Firefox users with private and secure encrypted Domain Name System (DNS) services through Mozilla’s Trusted Recursive Resolver (TRR) Program.”

Mozilla has been one of the companies on the forefront of protecting user privacy. One of the areas they have been focusing on is encrypting DNS traffic, which helps protect browsing activity from collection, interception or manipulation. For this to work, however, it requires partner companies to agree to standard rules about how data is collected, protected and used.

While companies like Cloudflare and NextDNS have signed on to Mozilla’s TRR Program, Comcast is the first ISP to sign on.

“We’re proud to be the first ISP to join with Mozilla to support this important evolution of DNS privacy. Engaging with the global technology community gives us better tools to protect our customers, and partnerships like this advance our mission to make our customers’ internet experience more private and secure,” said Jason Livingood, Vice President, Technology Policy and Standards at Comcast Cable.

“Comcast has moved quickly to adopt DNS encryption technology and we’re excited to have them join the TRR program,” said Eric Rescorla, Firefox CTO. “Bringing ISPs into the TRR program helps us protect user privacy online without disrupting existing user experiences. We hope this sets a precedent for further cooperation between browsers and ISPs.”

This is good news for Comcast and Firefox users. Hopefully Comcast won’t be the last ISP to sign on with Mozilla’s TRR Program.
