How to Enable or Disable DNS over HTTPS (DoH) in Firefox
When you type a web address or domain name into your address bar (example:www.tenforums.com ), your browser sends a request over the Internet to look up the IP address for that website.
Traditionally, this request is sent to servers over a plain text connection. This connection is not encrypted, making it easy for third-parties to see what website you’re about to access.
DNS-over-HTTPS (DoH) works differently. It sends the domain name you typed to a DoH-compatible DNS server using an encrypted HTTPS connection instead of a plain text one. This prevents third-parties from seeing what websites you are trying to access.
DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver. Encryption by itself does not protect privacy, encryption is simply a method to obfuscate the data. As of March 2018, Google and the Mozilla Foundation started testing versions of DNS over HTTPS.

B) Select Cloudflare or NextDNS in the Use Provider drop menu.
If you would like to use a different DoH provider than Cloudflare or NextDNS, select custom in the drop menu instead, and enter the URL address of the DoH provider you want to use.
C) Click/tap on OK, and go to step 7 below.
This is the default setting.
A) Uncheck Enable DNS over HTTPS in the Connection Settings dialog box. (see screenshot below)
B) Click/tap on OK, and go to step 7 below.
7 You can use Cloudflare's Browsing Experience Security Check page to test whether you are using Secure DNS for encrypted DNS transport with DoH. (see screenshot below)
That's it,
