DuckDuckGo has added built-in blocking for most video ads on YouTube in its browser, and the feature is enabled by default for iPhone and Mac users on the latest app versions. Multiple outlets report that the blocking targets pre-roll ads that play before videos start and other interruptions that can occur during playback, while maintaining core YouTube functionality such as viewing history and saving your spot in playlists.

DuckDuckGo says it uses community-maintained filter lists associated with uBlock Origin, along with its own compatibility rules to reduce site breakage. The company warns that users may experience slightly longer buffering times or occasional playback hiccups, but that video playback generally continues normally once a clip loads.

Some reports also note that the YouTube ad-blocking feature does not apply when a user opens YouTube links in the dedicated YouTube mobile app; in that case, the ad-blocking works only when users view YouTube content inside DuckDuckGo’s browser. Several outlets also mention that this YouTube ad-blocking feature is separate from Duck Player, DuckDuckGo’s distraction-free viewing mode, though both can be enabled together.
