DoH with Firefox

    Has anyone been able to get DoH to work with Firefox?  Firefox now supports it but it doesn’t seem to work with CleanBrowsing:  I have tested it with others such as AdGuards: and am able to get it to work. Wondering if there is a known issue.  Also is it possible to get the fallback or bootstrap IP for the DoH with CleanBrowsing?  Firefox has three settings that can be set along with a ttr mode setting as to if it will require DoH always or not.

    I have it working here without any issues.

    I set the bootstrap address to

    We recommend the trr mode to be set to 2 or 3 if enabled.

    I have it working now with both the bootstrap IP above entered above and trr mode set to 3.  Appreciate it!

    I saw a posting in the “News” forum that one will not be able to override the CleanBrowing filter in Firefox’s DoH settings. My understanding is that Chrome now provides a similar experimental DoH capability. Will the Chrome setting override the CleanBrowsing filter?

    Nope, we are working with the Chrome team and they will honor your CleanBrowsing settings.

    I tried to use the “Family Filter”
    with DNS:
    but it did not block any content when accessed through VPN app.
    What might be the reason for this?
