In May 2022, a report from Bleeping Computer by security researcher Zach Edwards found that DuckDuckGo's web browser allows Microsoft's trackers to continue running while visiting non-DuckDuckGo websites, contrary to Google and Facebook trackers, which are blocked. In response, Weinberg said that "this issue is occurring on browsers and only pertains to non-DuckDuckGo websites.", adding that "When you load our search results, you are completely anonymous, including ads", and that "Unfortunately our Microsoft search syndication agreement prevent us from doing more to Microsoft-owned properties. However, we have been continually pushing and expect to be doing more soon.", adding that "What we're talking about here is an above-and-beyond protection that most browsers don't even attempt to do — that is, blocking third-party tracking scripts before they load on 3rd party websites. Because we're doing this where we can, users are still getting significantly more privacy protection with DuckDuckGo than they would using Safari, Firefox and other browsers."
