Indeed, the policy can be used to disable DoH and please keep in mind that DoH is not being deployed on ESR.
More details on the DoH roll-out: - SUMO page https://support.mozilla.org/en-US/kb/configuring-networks-disable-dns-over-https - ESR will NOT be impacted - We're targeting rapid release users on 69 with IP addresses located in the US. We're NOT enabling DoH if any enterprise policy is detected, and if the enterprise roots pref is enabled. However, the proper way is to set the DoH enterprise policy to disable it. Administrators can also add exceptions, if they like DoH but it can break specific sites (e.g. because of split-horizon) On Mon, Sep 9, 2019 at 9:10 AM Philipp Madersbacher < [email protected]> wrote: > Hello, If your main intent is to centrally manage/disable DoH in Firefox, > you can easily do so through a GPO - the relevant links for this are: > > https://support.mozilla.org/en-US/kb/customizing-firefox-using-group-policy-windows > > https://github.com/mozilla/policy-templates/blob/master/README.md#dnsoverhttps > > No need to make the matter more complicated than it is ;-) > > Best regards > > Am So., 8.
