How to Enable DNS Over HTTPS in Firefox



Online privacy is important to anyone especially when you have private information on a cloud or passwords to online accounts. While the Internet can indeed offer privacy through reliable encryption, there are improvements that promises better security and this is what DNS over HTTPS (DoH) is all about.

What is DNS Over HTTPS?

DNS is a database that changes your online searches into a series of numbers called IP address to make it computer friendly. For example, if you type in the name of a website, it is like to an IP address that the computer understands so it can look up or find the website for you. This makes searches effective and easier.

However, the original process of DNS look ups are also performed on encrypted sites even without encryption. If that is the case, it is prone to potential hacking.

DNS over HTTPS is a new feature that resolves this encryption problem. It aims to improve the reliability and security of DNS look ups in your browsers. Through the process, users can use DNSCrypt, or switch to a different DNS provider. As of now, DNS over HTTPS is under testing by Mozilla, Google, and Cloudflare.
