With a pi hole, you’re basically setting up a DNS server that has built in abilities to stop ads.

What that means is, you can point your router (or any device really) at that DNS server (pi hole) to block ads.

Ublock is good.

Due to remote work constraints, a pi hole doesn’t play nicely with their stuff and I can’t be bothered to figure out a work around. Mostly because it’s my wife’s remote work, and their IT is hesitant to talk with me about it - I get it, I wouldn’t do that at work (I’m in IT).

So I use ublock on Firefox on both my desktop and phone, plus I run through a VPN that blocks ads and malware for everything else. The VPN is a separate use case, but that’s just an added benefit.
