How to enable DNS-over-HTTPS (DoH) in Firefox
The below step-by-step guide will show Firefox users how to enable the feature and not wait until Mozilla enables it
💡 Step 1:
Type about:config in the URL bar and press Enter to access Firefox's hidden configuration panel. Here users will need to enable and modify three settings.
💡 Step 2:
The first setting is network.trr.mode. This turns on DoH support. This setting supports four values:
✅ A value of 2 works best, however keep in mind that this is suspectible to downgrade attacks.
💡 Step 3:
The second setting that needs to be modified is network.trr.uri. This is the URL of the DoH-compatible DNS server where Firefox will send DoH DNS queries. By default, Firefox uses Cloudflare's DoH service located at
💡 Step 4:
The third setting is optional and you can skip this one. But if things don't work, you can use this one as a backup for Step 3. The option is called network.trr.bootstrapAddress and is an input field where users can enter the numerical IP address of a plaintext DNS resolver.
For example,
Normally, the URL entered in Step 3 should be enough, though.
Settings should apply right away, but in case they don't work, give Firefox a restart.

The first setting is network.trr.mode. This turns on DoH support. This setting supports four values:
0 - Default value in standard Firefox installations (currently is 5, which means DoH is disabled)1 - DoH is enabled, but Firefox picks if it uses DoH or regular DNS based on which returns faster query responses2 - DoH is enabled, and regular DNS works as a backup3 - DoH is enabled, and regular DNS is disabled5 - DoH is disabled✅ A value of 2 works best, however keep in mind that this is suspectible to downgrade attacks.
💡 Step 3:
The second setting that needs to be modified is network.trr.uri. This is the URL of the DoH-compatible DNS server where Firefox will send DoH DNS queries. By default, Firefox uses Cloudflare's DoH service located at
https://mozilla.cloudflare-dns.com/dns-query. However, users can use their own DoH server URL. They can select one from the many available servers, from this list, here. The reason why Mozilla uses Cloudflare in Firefox is because the companies reached an agreement following which Cloudflare would collect very little data on DoH queries coming from Firefox users.💡 Step 4:
The third setting is optional and you can skip this one. But if things don't work, you can use this one as a backup for Step 3. The option is called network.trr.bootstrapAddress and is an input field where users can enter the numerical IP address of a plaintext DNS resolver.
For example,
91.239.100.100 (uncensoreddns.org "anycast").Normally, the URL entered in Step 3 should be enough, though.
