Just getting started with DNS over HTTPS (DoH)? No need to worry! We have outlined a list of FAQs here that you may find helpful while getting up to speed with all that DoH has to offer. For additional information, see [[Firefox DNS-over-HTTPS|Firefox DNS-over-HTTPS]]. __TOC__ =Will users be warned when this is enabled and offered an opt out?= Yes, a pop-up will display so that you can opt out. This pop-up won’t go away until dismissed (or Firefox is restarted). =Can users opt out ahead of time and not have their setting changed by Mozilla?= Yes, you can set {pref network.trr.mode} to {pref 5} manually in the [[Configuration Editor for Firefox|about<nowiki>:</nowiki>config]]. Additional information about the modes can be found [https://wiki.mozilla.org/Trusted_Recursive_Resolver#network.trr.mode here]. =Are there other providers coming to the Firefox selection soon?= We have some ongoing conversations, and will announce more providers in the near future. CloudFlare will remain the default for new users in the US. =What about enterprises with custom DNS solutions?= We have made it easy for enterprises to disable this feature. Firefox will detect whether enterprise policies have been set on the device and will disable DoH in those circumstances. If you’re a system administrator who is interested in learning how to configure enterprise policies, please review the documentation [https://support.mozilla.org/en-US/products/firefox-enterprise/policies-customization-enterprise/policies-overview-enterprise here].
