Google is closing the last technical escape routes that allowed older ad blockers to evade its Manifest V3 migration, which restricted the extension API that made content-blocking tools effective. This leaves users with only limited blockers or ones that require constant manual rule updates, completing Google's years-long project to make ad blocking technically harder on its dominant browser. The move exposes the vulnerability of relying on a single company's platform—Chrome controls two-thirds of browsers—to define what blocking technology is permitted.
