Chrome’s MV3 Switch Slams the Door on Traditional Ad Blockers

Google is switching Chrome from MV2 to Manifest V3, which will end official support for MV2 extensions and effectively disable popular ad blockers such as uBlock Origin; MV3 caps filtering and removes dynamic blocking, limiting ad-blocking effectiveness, though it doesn’t ban blockers outright. A Lite version of uBlock Origin exists with reduced functionality. Other browsers may continue MV2, but Chrome’s transition is slated to roll out with Chrome versions 150–151 this summer.
