DuckDuckGo’s (DDG) privacy-focused web browser permits Microsoft tracking scripts on third-party websites, which was revealed in May, and the firm now claims it will begin blocking them as well. DuckDuckGo’s browser previously featured third-party tracker loading protection that disabled scripts embedded on webpages from Facebook, Google, and others, but Microsoft’s scripts from the Bing and LinkedIn domains (but not its third-party cookies) were exempt until now.
A security researcher named Zach Edwards pointed out the exclusion, which he apparently discovered when auditing the browser’s privacy claims, and noted that it is particularly strange given that Microsoft is the partner that delivers ads in DDG’s search engine (while promising not to use that data to create a monitored profile of users to target ads, instead relying on context to decide which ones it should show).
