Hello team, We've deployed a GPO to change Firefox setup to use our DNS over HTTPS with a custom Cloudflare URL. The registry settings are: HKLM\Software\Policies\Mozilla\Firefox\DNSOverHTTPS\Enabled = 0x1 HKLM\Software\Policies\Mozilla\Firefox\DNSOverHTTPS\ProviderURL = "https://modifiedentry.cloudflare-gateway.com/dns-query" HKLM\Software\Policies\Mozilla\Firefox\DNSOverHTTPS\Locked = 0x1 When looking into Firefox policies it seems to be applied correctly: about:policies Active Policy Name Policy Value DNSOverHTTPS Locked true ProviderURL "https://modifiedentry.cloudflare-gateway.com/dns-query" This doesn't work, but manual setup from Firefox Settings using the same URL does. Any clue why this could be failing? Thanks in advance
