I think this is a horrible idea and applications should respect the OS DNS configuration. I have already configured the instance of dnsmasq on my router at home to return NXDOMAIN for the canary domain. That being said I am a little confused by those that are concerned because this change would mean their DNS queries will be sent to a US company and they don't trust US companies. Firefox is developed and distributed by a US corporation and is just a susceptible to being forced to follow US government directives as Cloudflare.
