Please explain your choices. TH. ___________________________________ I use the same DNS provider (Quad 9) in the browser and in the system. I think a different DNS provider in the browser might be more difficult to manage.
It's complicated. On system level: 1. I use non-filterring Cloudflare DNS for domains under country code top-level domain of country I live in and also .eu domains, except Google. 2. Google DNS for Google services. 3. Everything else OpenDNS On my most commonly used Firefox profile I disabled DoH. I use local resolver on local loopback interface that is also used on system level. On other Firefox profiles such as for Facebook or logged-in YouTube usage etc I use either DoH by Quad 9 or Goole DNS, or OpenDNS. This intentionally by-passes filtering by local resolver.
I'm using the same DNS server for my whole system. The respective server is fastest at the time of the dnscrypt or DoH servers automatically determined by dnscrypt-proxy.
I have the same DNS in browser, windows, and Kaspersky Cloud, but windows does not have the DoH server.
I just use my ISP'S DNS, I prefer to keep things simple, minimal programs installed on my computer, no Hosts files, excessive tweaking of browsers or adblockers. I don't want maintaining my protection to be a full time job.
If I set a DNS in Windows, the browsers simply ignore it, so I use DoH in the browsers (Aha DNS w/ ad blocking at the moment).
