Firefox using Apple Private Relay DNS

Hello,

I'm trying to get my Firefox on Mac to use the DNS supplied by my DHCP. If I have Apple's Private Relay turned off, everything works correctly. However, if Apple's Private Relay is turned on, then Firefox will use Apple's Private Relay DNS (Cloudfare in my location). I have confirmed it's a configuration problem in Firefox because Chrome uses the correct DNS, and so does dig in the terminal.

I have tried:

  • Resetting Firefox to default settings
  • Uninstall and reinstall Firefox, including deleting the Firefox folder that contains the Profiles folder and profiles.ini file
  • Clearing cache and Firefox DNS at about:networking#dns
  • In Network Settings, tried 'No Proxy', 'Auto-detect proxy settings for this network', and 'Use system proxy settings'
  • Confirmed Enable DNS over HTTPS is not checked (If I check it, then it does work correctly, but that isn't my goal)

Thanks for any help!
