Manifest V3 comprises a major change to Chrome’s extensions system, including a revamp to the permissions system and a fundamental change to the way ad blockers operate. In particular, modern ad blockers, like uBlock Origin and Ghostery, use Chrome’s webRequest API to block ads before they’re even downloaded.
With the Manifest V3 proposal, Google deprecates the webRequest API’s ability to block a particular request before it’s loaded. As you would expect, power users and extension developers alike criticized Google’s proposal for limiting the user’s ability to browse the web as they see fit.
Google is essentially saying that Chrome will still have the capability to block unwanted content, but this will be restricted to only paid, enterprise users of Chrome. This is likely to allow enterprise customers to develop in-house Chrome extensions, not for ad blocking usage.
