@davidbisset I'm a bit confused about some of the article though. Like they show some such as LibreWolf making only three connections on initial install, but then go down to list a bunch of connections, most of which are obviously extensions making the connection.
They also say they're not talking about what is good or not, but then explicitly declare that making connections is bad and I must strongly disagree when some of those connections clearly shown are for uBlock Origin to download its blocklist (that's a minimum standard! You should never browse the Web without an ad blocker in 2025!) It's good for you to start off with a bare minimum safety margin, otherwise even just that quick lookup of something before initial setup is dangerous.
