Best YouTube Ad Blockers That Still Work

Finding a YouTube ad blocker that still works is harder than blocking ads anywhere else. Videos and ads are served from the same domains, so a blocker cannot simply cut an ad server — it has to understand the page well enough to tell them apart. That arms race is why every YouTube ad blocker breaks every few weeks, and why "which one still works" has an expiration date on the answer. Here is the current picture and, more usefully, the routine that keeps whatever you use working.

What still works

Three approaches currently hold up on YouTube:

1. uBlock Origin (Firefox) remains the most resilient option because Firefox lets extensions modify requests the way uBlock needs. Its filter lists are updated within days of each YouTube change.
2. AdGuard (app or extension) maintains its own YouTube-specific filter set and tends to recover fastest after major breakages on Chrome, where Manifest V3 limits extension APIs.
3. Premium, if you watch enough that the maintenance bothers you — the only option that cannot break.

Chromium's Manifest V3 caps the request-blocking APIs classic blockers rely on. Extensions there keep working but recover from YouTube changes slower. If YouTube is your main use case and you are on Chrome, Firefox plus uBlock Origin is the pragmatic answer.

Why they break every few weeks

YouTube experiments with ad delivery continuously. When an experiment ships, filter-list maintainers write new rules, the lists update, and blockers heal — usually within two to five days. So "my blocker stopped working on YouTube" almost never means broken software. It means the lists have not caught up, or yours have not refreshed. Update lists first, panic later.

The maintenance routine

• Update filter lists weekly (uBlock: Dashboard → Filter lists → Purge all caches → Update now).
• After any browser update, run a general ad blocker test to confirm the extension is still enabled and functional.
• If pre-rolls return only on YouTube, check the blocker's GitHub issues — you will usually find a fix-in-progress thread and a temporary filter to paste.

FAQ

Is blocking YouTube ads against the terms of service?

YouTube's terms discourage it, and the platform periodically warns some users. Enforcement against individual viewers has been rare and limited to nag screens. Know the trade-off and decide for yourself.

Do ad blockers slow YouTube down?

The opposite, usually. Blocking ad requests removes work from the page. The exceptions are poorly maintained blocker-plus-antivirus stacks that double-filter everything.
