How to Use DNS Over HTTPS in Firefox

DNS Over HTTPS (DoH) has a function to maintain user privacy when browsing the internet by encrypting the network of the domain being visited. This is different from a VPN, where the IP address you use will remain and do not change.

Basically, even in Windows 10, DNS Over HTTPS can already be applied, it’s just that for now users have to activate it manually via registry. While the easiest way to use DoH is through a browser.

Popular browsers such as Firefox, Chrome, and Opera already have a feature to use DNS Over HTTPS. By default this feature not active right awaybut you can enable it and set the DNS as expected.

To make Firefox DoH fully functional, I suggest restarting the browser and then trying to access a website again. if there are no problems when accessing a website, it means that you have successfully activated DoH in Firefox.

Meanwhile, if the website cannot be accessed, it means that you are having problems setting up DoH. Please double-check the DNS service you chose. Make sure it’s set up correctly, or please try using Cloudflare first to make sure it works.
