Google's Chrome browser is set to introduce Manifest V3, a new extension platform that will limit the capabilities of ad blockers, making it harder for them to quickly respond to changes in ad delivery. This move is seen as part of Google's efforts to reduce the effectiveness of ad blockers, which could lead to more ads being displayed to users. The new platform will require ad blockers to update their filter lists through the Chrome Web Store, which can take several hours to several weeks, giving YouTube an advantage in the cat-and-mouse game of ad blocking. This change is scheduled to become mandatory in June 2024.
