Make sure that's something you want to do. While it may add some privacy protection from your ISP, you're only shifting that trust to the DoH provider. Keep in mind that by using DoH you're sending all your queries to a single provider, probably Cloudflare unless you choose another provider that supports DNS over HTTPS.

At the bottom of the window you will be able to select 'Enable DNS over HTTPS' and choose a provider: On the General page of your preferences, scroll down to and open Network Settings. They keep your DNS queries private from your ISP, and they make sure they aren't tampered with in transit between your DNS provider.įortunately, Firefox recently added native DoH support to the browser. Because computers can only make connections to IP addresses, it's necessary to use DNS every time you visit a new domain.īut DNS is unencrypted by default, that means everyone on your network (including your ISP) can view what domains you're looking up, and in some situations even change the IP answers to redirect you to their own websites! Encrypting your DNS traffic can shield your queries and add some additional protection to your browsing.Įncrypted DNS takes many forms: DNS over HTTPS (DoH), DNS over TLS, DNSCrypt, etc., but they all accomplish the same thing. Enable DNS over HTTPSĭNS (or the Domain Name System) is what your browser uses to turn domain names like privacytools.io into IP addresses like 145.239.169.56.

This will likely log you out of websites quite often, so make sure that's an inconvenience you're willing to put up with for enhanced tracking protection.
