Background
Ad blockers are tools that help keep our online browsing free from disruptive ads and protect our privacy by blocking trackers—tiny codes that collect data about what we do online. They work like a digital shield, allowing users a more pleasant and secure browsing experience.
History
For years, ad blockers have been using a system called manifest version 2, relying on powerful tools like the WebRequest API to block unwanted ads and trackers. Google’s latest update to manifest version 3 introduced a new approach using the DeclarativeNetRequest API, sparking fears that such changes could weaken ad blockers’ abilities—which past updates sometimes have done. However, this study shows that these fears were largely unfounded.
