Not part of any adblocker. Some, like Ghostery, have a separate mechanism to auto-reject these. I switched from uBO to Ghostery because uBO wasn’t doing anything against those.

this is false. and instead of just claiming so, here is proof: there are built-in (but disabled by default) blocklists specialized for cookie prompts and such

That’s not an adblock feature

and as I said, uBO is not just an ad blocker, so saying xy ad blocker can replace it well is false.

and there are hundreds of other extensions that handle that, like PrivacyBadger

except that not really. Because again, the required browser APIs were removed, and even before that, privacy badger was not so effective

Also: privacy related stuff is not affected by Manifest v3, no?

everything is effected that:

• needs to block network requests, including loading of certain site scripts
• depends on an up to date list of things to block
