Earlier quoted context omitted.
DNS based adblockers have strictly worse adblocking capabilities than manifest v3 adblockers. I mean, sure they have their uses (eg. blocking ads/telemetry in apps or whatever), but bringing them up in this context doesn't really make sense.
I thought the whole issue with manifest v3 is that prevented extensions from being able to block connections? That DNS blocking is actual blocking, while the extension can only do filtering after the connections are made.
No. See:
https://developer.chrome.com/docs/extensions/reference/api/d...
>The chrome.declarativeNetRequest API is used to block or modify network requests by specifying declarative rules. This lets extensions modify network requests without intercepting them and viewing their content, thus providing more privacy.
