About this tag
The masked domain list (MDL) is a list-based mechanism used by Google Chrome to block third-party scripts known for browser fingerprinting, particularly in Incognito mode. This approach, part of Chrome's Script Blocking in Incognito feature, relies on the MDL to identify and block fingerprinting scripts, enhancing user privacy.
