Hello, this does not apply to me but I'd like to say my 2 cent regardless:
Your boss cannot be your friend (or vice versa). It simply does not work out well, you can't be a leader while being friends with your followers, so I expect everyone who worked for their friends will most likely describe it as a miserable experience.
They're not only living off google money, they also fired all their engineers, and google is required by court of law to supply money and engineers to help maintain Firefox, ridiculous!
He needs to disable DoH in order to avoid firefox using HTTPS to conduct the DNS queries. This is needed if he wants to block the request through his system hosts files or firewall.
