Enable or Disable DNS over HTTPS in Firefox, Chrome, and Edge

Mozilla has started rolling out DNS over HTTPS for Firefox to make sure the DNS resolution is also secure. While there is more to it, in this post, we will show how you can disable or enable DNS over HTTPS protocol in Firefox, Chrome, and Edge. That said, while Firefox offers extensive configuration for DoH, Chrome and Edge only offer basic settings.

What is DNS over HTTPS (DoH)?

In simple words, like how HTTPS makes sure data sent and received between servers are encrypted, DNS over HTTPS means any query sent to the DNS resolver is secured as well. The process makes sure any ISP or a hacker keeping a tab on Public WiFi is not able to see your requests.

The only drawback enabling DNS over HTTPS is that it bypasses features offered by Home DNS which filters out spam, and contents that are not fit for kids.

Since both are based out of Chromium, they use the same flags to enable and disable the feature.

  • In Chrome open  chrome://flags/ in a new tab and on Edge use edge://flags/
  • Type DNS over HTTPS in the search box, and it will reveal Secure DNS lookups flag
  • Change from default to enabled.

When the feature is enabled, the browser will use a secure HTTPS connection to look up the addresses of websites and other web resources. It is applicable for Mac, Windows, Chrome OS, Android

  4. Once available, click the Edit button next to the preference.
  5. Add domains, separated by commas, to the list
  6. Click on the checkmark to save the change.

To disable DNS over HTTPS, disable the settings you turned on. I hope the post was easy to follow, and you were able to enable or disable DNS over the HTTPS feature in Firefox, Chrome, and Edge.
