Hi, I would like to know which version of Mozilla used this setting of network.trr.excluded-domains: 'sbl-xbl[.]spamhaus[.]org, localhost.that.never.exists'. The default is 'undefined' as I checked in 127.0.1 and the older 124. I also contacted support of extensions that I used, no evidence of both excluded domains. Can anyone help me? Thanks a lot \!o!/

Firefox only comes with the network.trr.builtin-excluded-domains pref. The network.trr.excluded-domains pref is used by extensions or third-party software (policies) to excluded more domains, so you can stop looking for it in Firefox.
