I don't know how it actually works, but won't website like youtube simply deny you access if it detects that the ad related request timed out? I imagine that browser extensions actually tap into the site's code and somehow go around such detection. But if this is a simple firewall, how will this work against any website that doesn't just default to most trivial "import ad service", but rather actually takes steps to block the ad blockers (Like youtube)?
