How hard would it be to "wrap" the browser in a ublock like shell, so that all network requests are filtered through a firewall before they even reach the chrome application layer.

It might be easier to maintain than an actual extension interface with hooks thought the code.

I don't think you'd need manifest V2 for such a rudimenty logic.

The reason why ublock origin is so powerful is because it works with the DOM/not at the network level and can use heuristics to determine wherever something is a advertisement or not.

I imaged you would use both.
