Hidden page elements

  • Ad-shaped boxes on the pagetesting

Only extensions can hide elements; DNS blockers can’t.

Requests go out without cookies or a referrer. A host that isn’t blocked receives one request from your browser, the same as on any site that uses it.

Where to block

Each layer catches different things. The strongest setup combines an extension in your browser with encrypted DNS on every device.

One browser

Browser extension

Good at: The most precise layer. It blocks page elements as well as requests, including ads the site serves itself, like YouTube’s.

Misses: Per browser, per device. Doesn’t reach other apps.

A whole device

Encrypted DNS

Good at: Covers every app on the phone or computer, and you set it up once. Free tiers are enough for most people.

Misses: Blocks whole domains only, so can’t remove ads served from the same domain as the content, or hide empty ad boxes.

  • NextDNS Custom blocklists and logs you control.
  • AdGuard DNS Free public resolver or a configurable account.
  • Mullvad DNS Free, no account, several blocking levels.
  • Quad9 Blocks malware and phishing domains, not ads.

Every device at home

Network-wide

Good at: Covers smart TVs, consoles and guests’ phones too, with nothing to install on them.

Misses: Needs a small always-on computer and some setup. Stops working when you leave the house.

  • Pi-hole Runs on a Raspberry Pi or any Linux box.
  • AdGuard Home Single program, easy web setup, encrypted DNS built in.

Chrome, Manifest V3 and uBlock Origin

Chrome has switched off extensions built on the old Manifest V2 platform, including the full uBlock Origin. Its replacement, uBlock Origin Lite, follows Chrome’s new rules. It blocks most ads and trackers, but it can’t update its filters between releases or run some of the original’s advanced filters.

Firefox still supports the full uBlock Origin, on desktop and Android. On Chrome, pair uBlock Origin Lite with encrypted DNS, or switch browser.
