Chrome’s controversial new extension platform is coming in 2023

Google has been slowly but surely moving towards a new extension platform called Manifest V3 for Chrome.Now there is a company timeline launched for it. Starting with Chrome 112 in January 2023, the company may start turning off support for Manifest V2 in the Canary, Dev, and Beta channels. Then in Chrome 115 in June, it will also start trying to turn off support in the stable channel.

To coincide with the transition from Chrome stable to V3, all Manifest V2 extensions in the Chrome Web Store will be switched to unlisted. Eventually in January 2024, the remaining V2 extensions will be completely removed.

Transition is not without dispute However. While Manifest V3 contains a slew of changes, many of which Google claims are made in the name of privacy and security, its impact on ad blockers is particularly irritating. It basically stops them from working like they are and makes them pretty much useless.

Most modern ad blockers (like uBloc Origin and AdGuard) rely on Chrome’s “webRequest” API to block all classes of HTTP requests. But this approach significantly delays website loading and rendering times, something Google is apparently eager to avoid. Instead, Manifest V3 requires developers to use “declarativeNetRequest”, which essentially forces them to use a blocklist for specific URLs. The problem is that the “rules” list is limited to 30,000 entries. Many ad blocker lists may exceed 300,000 entries.

Business users At least some relief, and will be able to continue using the Manifest V2 extension until January 2024.
