Manifest v3 is designed to make ad-blocking much harder. First off the filter lists will be distributed as part of the extension itself, which means that updates will be much less frequent (review can take multiple days, even multiple weeks) and certain types of blocking (e.g. YouTube ad blocking) will be completely impossible.
This gives ad networks a big leg up - they can either use techniques like Google does for YouTube ads to circumvent your ad blocker, or rotate domains etc. fast enough that extension updates are too slow.
