GOOGLE is removing all Manifest V2 (MV2) browser extensions by August 31, 2026, including popular ad blockers like uBlock Origin. This change is part of Google's push towards Manifest V3 (MV3), aimed at improving security and reducing resource usage for extensions, albeit at the cost of some filtering capabilities. Since 2025, MV2 extensions have faced increasing restrictions, making installation difficult.
Users reliant on these extensions should back them up before removal, with steps provided for downloading CRX files. Developers can consult the official MV2 deprecation timeline for detailed phases.
