It's interesting because I've heard Manifest 3 was an effort to not make extensions quite have full trust capability and isn't as odious as it sounds but it's also Google, so...
Have you tried using Manifest V3 adblockers on Chrome? They're not nearly as capable or useful as the old ones.
Ah Manifest 3: Will still happily allow an extension to silently transmit all of your browsing and AI chat history to data brokers to be packaged and sold to the highest bidder.
While conveniently and regrettably unavoidably nerfing ad blockers :(
For your safety of course.
