Chrome's Manifest V3, and its changes for ad blocking, are coming real soon

Google Chrome is set to implement its new extension platform, Manifest V3, which has been in development for six years. Users of popular ad-blocking extensions like uBlock Origin are receiving warnings that these extensions may soon be unsupported. Manifest V3 will require extensions to comply with new guidelines, with the transition for V2 extensions beginning in early June 2024. Google claims the new platform aims to enhance security, privacy, and performance, although critics, including the Electronic Frontier Foundation, argue that it may not significantly improve security. A major change involves the prohibition of "remotely hosted code," which affects how ad blockers update their filtering lists, requiring them to go through the Chrome Web Store's review process. This has raised concerns among developers who view it as a form of gatekeeping. While Google asserts that it is not eliminating ad blockers but making them safer, the changes have led to the development of a "Lite" version of uBlock Origin that will comply with Manifest V3, albeit with reduced functionality. The transition for enterprise users is expected to be delayed until June 2025.
