My experiences with Pi-hole (scribe.disroot.org)

Pi-hole has helped improve my "relationship" with Firefox, or better phrased with Firefox forks like LibreWolf and Tor browser. Cool thing with Pi-hole is that you can watch the query log and see what happened in the background while you were surfing the Internet. I learned that :

After removing the sponsored shortcuts in Firefox and putting your own shortcuts there Firefox will make connections each time you start the browser. So, if you would have icons on your quick start page in Firefox for let's say EFF, Lemmy, Mastodon, HackerNews, with each Firefox start up, it would query these sites. which I didn't like so much. Since then I've gone back to a complete blank start page, removing search and all those quick start icons, using just toolbar folders with bookmarks.
Pi-hole defaults to blocking telemetry for Firefox and Thunderbird.
Signal uses Google servers I saw via Pi-hole. I thought that they were using Amazon servers, but looking at Wikipedia for the history of Signal hosting I learned that Signal went back to Google for hosting.
Firefox push notification services are hosted on Google servers. LibreWolf removes a lot of Google things that Firefox has by default, but not the push parts. With Pi-hole it is very easy to block that.

Pi hole is an amazing tool and gives a lot of insight on what is being queried and blocked against the block lists. Also, makes completely transparent on the entire network to have nasty things blocked. One thing I will mention to make the setup better: make sure on the firewall level you can have a rule that makes every request for a DNS to go through pi hole. Some devices will use a hard coded DNS instead of respecting the one on the network

Dns over https is immune to that firewall method, right?

Yes but I think OP is referring to plain DNS requests to a preferred server.

You can hijack port 53 and redirect them to your preferred server. Also acts as a method of hardening DNS for devices and apps that do not support encrypted DNS.

Forgot to mention the port but that's it. Notorious devices like smart TVs and consoles like to use the hard coded DNS method
