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.
Media players, TVs, IP cameras, lightbulbs… anything with wifi capability really.
Is there a safe way to use these devices? I’m moderately tech savvy at best, and I do worry a lot about my tv. I also use some smart plugs to manage equipment on my aquarium, but that’s it. I’ve considered the implications of these devices, but didn’t know if there was anything I could do about it.
