Do you prefer the Chrome web browser to Firefox web browser, here’s an important update that you need to be aware of. Starting today, developers of Mozilla is activating the DNS-over-HTTPS security feature bu default for all Firefox users.
The developers explained that from now onwards, Firefox will send all your DNS queries to the Cloudflare DNS servers set by your operating system, router, or network provider.
As you may know, DNS-over-HTTPS (DoH) protocol performs DNS lookups — i.e., finding the server I.P. address of a certain domain name — over an encrypted connection to a DNS server rather than sending queries in the plaintext.
According to Mozilla, this privacy-focused technology makes it harder for man-in-the-middle attackers, including your ISPs, to manipulate DNS queries, eavesdrop on your Internet connection, or learning what sites you visit.
“This helps hide your browsing history from attackers on the network, helps prevent data collection by third parties on the network that ties your computer to websites you visit,” the company said.
To enable this new feature go to Firefox Settings > Preferences > General > scroll down to Network Settings > click Settings > then click Enable DNS over HTTPS.
“We continue to explore enabling DoH in other regions and are working on adding more providers as trusted resolvers to our program. DoH is just one of the many privacy protections you can expect to see from us in 2020.”
Anyway, Mozilla has now become the first browser to push DNS-over-HTTPS by default, and the company has plans to gradually roll it to the rest of the Firefox users in other countries in the next few months.
