Haven't used adblocker extension for a while. I just have AdGuard Home on a VPS to be used with every device on the network and do DNS level blocking and all is clean including stopping trackers from non browser apps.
DNS-based solutions can't block everything since they're limited to blocking domains. But wait until we bring a content filtering proxy to AdGuard Home, this will be the day when you'll finally get clean pages and you won't need any extension at all for that.
