How to Enable Firefox’s More-Secure DNS Over HTTPS Feature Before Mozilla Does
Mozilla will enable Firefox’s DNS over HTTPS (DoH) service by default for all users at some point in late September. Here’s why that’s important: DoH keeps your internet browsing private and secure by hiding DNS requests—from your ISP, from software on your system (like parental control apps or other blocking software), and from anything else that might try to suss out what you’re up to, like your government’s censorship mechanisms for web browsing.
DoH will soon be a default feature for a small subset of Firefox users once the update rolls out, and a broader rollout once everything is confirmed to work without issue. The feature also happens to be available in Firefox browsers right now for those who don’t want to wait—all it takes is a few tweaks in the settings menu:
- Open a new Firefox tab on desktop.
- Type “about:preferences#general” into the address bar and press Enter.
- Scroll down to Network Settings and click “Settings.”
- Scroll down and tick the box next to “Enable DNS over HTTPS.”
