I am using opendns as the dns server, set in the windows network adapter settings. This is on Windows 10, no parental controls are turned on. The release notes of 69.0.2 says a bug was fixed about parental controls: https://www.mozilla.org/en-US/firefox/6 ... n=whatsnew https://bugzilla.mozilla.org/show_bug.cgi?id=1584613
In 69.0.1 all was fine. With 69.0.2, opendns shows its blocked page for sites that parental control would block.
