Not asking for tech support here, just wondering if in theory it would be possible to create a plug-in or even a complete browser that blocks ads in a way that’s impossible to detect. One model that comes to mind is a quarantined / containerized non-blocking virtual browser which queries the web server directly, then the UX filters the content from that container and presents it to the user ad-free. As far as the web server can tell, the containerized browser is just vanilla Chromium.
An ad-blocking DNS server on your local network should work for apps too, right? (As long as the ads are hosted on known ad servers.)
Should, yes, but the page/site may have ways to detect if the ad loads or not and still trigger “adblock in use”.
A DNS-based approach also won’t work if the ads come from the same domain as the content.
