Google removes MV2 extensions, uBlock Origin included

What's this about?

Chrome Web Store has removed remaining Manifest V2 extensions, uBlock Origin among them. The migration has been announced, delayed and re-announced for years; this is the point where the listings actually stop existing.

What is Manifest V2 versus V3?

The manifest is the contract an extension declares with the browser: what it may do, what it may see. MV2 let an extension intercept a network request and decide, in its own code, whether to block it. MV3 replaces that with a declarative rule list submitted in advance — the browser does the blocking, from a capped number of static rules. Google's stated reason is performance and security, and both are real. The consequence is also real: an ad blocker can no longer make decisions at request time, which is precisely what the most effective blocking needs.

What's the community saying?

HN 563 points, 428 comments — the most-discussed thread of the day
  1. The top comment is two words: "switch to Firefox." It is the entire practical answer and everybody knows it.
  2. The thread escalates quickly into a broader boycott list, and then into whether any of this is worth using at all.
  3. An unexpectedly long and sincere sub-thread on returning to pen and paper for notes — several people argue it is a more creative medium, others that organising it is the problem.
  4. Underneath the venting is the structural point: this is what it looks like when the platform vendor also sells the ads.
