I realize that ESR 60 will be out of support soon, but we have folks trying to explicitly disable DNS on ESR 60 and it breaks DNS.

If you set network.trr.mode to 5, DNS lookups fail.

IMO this is wontfix. We have no more planned ESR 60.x releases and this is setting a preference to an unsupported value for that release.

I'm totally OK with that, just wanted it documented somewhere. The problem is here:

https://searchfox.org/mozilla-esr60/source/netwerk/dns/TRRService.cpp#110-111

The params to trr.mode aren't validated.

Marking WONTFIX since this is fixed in ESR 68.
