My approach today is Firefox with Enhanced Tracking Protection and then keeping Google, Meta/Facebook, and Amazon logins sequestered to individual containers. At that point a lot of the worst ad networks will complain that you are using "an ad blocker" simply because most of their trackers fail and won't even bother showing ads.

(Then on mobile, similarly using Firefox on iOS, being heavy and fast on the "ask app not to track" buttons and keeping logins to first party apps only and almost never in either Safari or Firefox.)

Again, I use no real "ad blocker", just the above steps.

It's probably not an approach for everyone, and entails a bit of paranoia to operate, but I think it sends the right message that I don't mind untracked/untargeted ads and don't think companies deserve my unfiltered data.
