> If uBlock Origin doesn't update, there'll be a dozen adblockers that work with Manifest v3 on day 1.

You seem to not know what manifest v3 is actually doing.

Any adblocker with a static list of domains per-update of the crx file's manifest is useless. Users would have to install hundreds of extensions (each with dozens of domains that they themselves block), just to have the same functionality.

If any anti adblocking team of any ad network decides to just rename foo.tracker.net to bar.tracker.net, all adblocker extension users would have to REINSTALL the chrome extension manually because the manifest's list of domain is statically builtin.

You're operating off of outdated information. Rules do not need to be baked into the manifest.

>The Declarative Net Request API now allows for the registration and removal of dynamic rules - specified at runtime rather than statically in the manifest. We’ve also added the capability to remove common tracking headers, such as Referer, Cookie, and Set-Cookie.

If its trivial what's stopping you from doing it?

Why would I need to? Manifest v3 isn't even out yet, and dedicated developers will easily beat me to the punch.

What? Manefist v3 is not even out yet...
