Does Firefox + Cloudflare DNS over HTTPS block queries to known malicious sites like OpenDNS. I use OpenDNS at home to automatically block queries to known malicious sites. Using Firefox DoH bypasses this. Am I faced with privacy versus security or does Cloudflare service also prevent access to malicious sites? Thank you.

hi, no the dns over https providers that are integrated into firefox do not block or filter particular domains (other than required by law), which is laid out in this policy: https://wiki.mozilla.org/Security/DOH-resolver-policy

firefox would depend on google's safebrowsing lists to protect you from connecting to known malicious sites: How does built-in Phishing and Malware Protection work?

you can also configure firefox to use opendns as a trusted resolver though: https://support.opendns.com/hc/en-us/articles/360038086532-Using-DNS-over-HTTPS-DoH-with-OpenDNS
