Firefox + uBlock origin on the desktop and Safari + AdGuard (browser extension, not DNS) on iOS. I also use the OISD (https://oisd.nl https://oisd.nl) blocklist for DNS level blocking with NextDNS. OISD prioritizes functionality over blocking, which is exactly the way I like it for DNS level blocking. Never had to manually whitelist anything.
