Why you should say "NO" to Cloudflare

Solutions - Change default DNS provider of firefox

Mozilla (Firefox) has partnered up with Cloudflare and will resolve the domain names from the application itself via a DNS server from Cloudflare. Cloudflare will then be able to read everyone’s DNS requests.

You can disable it in “about:config"

• The string value of "network.trr.uri" should be empty.
• The string value of "network.trr.resolvers" should be set to [].

Or in /distribution/policies.json` (Firefox ESR)

...
      "DNSOverHTTPS": {
         "Enabled": false,
         "ProviderURL": "https://0.0.0.0/"
      },
...

Some other settings can also contain Cloudflare URLs. It is recommended to search for "cloudflare". GNU Icecat and older Firefox versions(<68) are not affected yet.
