Overview
- DuckDuckGo announced Wednesday that its browser now blocks most preroll and midroll video ads on YouTube by default for iOS, Mac and Windows users with Android available via a manual setting for now.
- The feature works on YouTube’s website inside the DuckDuckGo browser and will not block ads if a link opens in the separate YouTube app.
- DuckDuckGo said the blocker matches video ad requests using uBlock Origin community filter lists supplemented by its own compatibility rules, and reviewers confirmed ad suppression in real-world tests.
- The company warns the blocker can cause slightly longer buffering and that effectiveness may lapse temporarily when YouTube changes how it serves ads until filter lists are updated.
- Because YouTube’s support pages say ad blocking violates its Terms of Service, DuckDuckGo’s change could prompt Google to deploy technical countermeasures or policy actions that would start a cat‑and‑mouse cycle over ad delivery.
