> Despite losing a small part of their functionality, ad blockers will still be able to offer nearly the same quality of filtering that they demonstrated with Manifest V2.

If some mechanism or capability is no longer possible or is made infeasible for adblockers to control, then ads will simply switch to using that mechanism. It's a pretty obvious outcome. You cannot simply give just an inch with adtech.

I would be interested to see a list of capabilities and features lost in MV3. For example, do we lose CNAME filtering or strict-blocking? It's not clear what we are losing.

The last time I check a couple of months ago these was the list of things that we lose (Things might have changed so I welcome correction from any kind)

- Now any block filter list will have be updated with a plugin update. So no fetching lists from links directly.

- strict blocking ability [1]

- No dynamic filtering [2]

- No Custom lists (own or third party by the user)

- Element Picker [3]

We lose the ability to innovate. The browser (Google) becomes the gatekeeper. And yes, we lose CNAME filtering.[1]

Google is an advertising company. Chrome extensions already experienced a lost decade, where nothing much happened until the Manifest V3 "proposal". It's not a good idea to let Google hold the keys to anti-tracking tech.

[1] I stand corrected, DNS lookups are not part of webRequest in MV2 Chrome either. This doesn't change my larger point.

But Chrome never had CNAME filtering before either

In my understanding, content blocking proxy should still work. For example,
