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.
If the site tries really hard, they can control serverside how many seconds of ad you watched to decide if you can access any content whatsoever. Something like this is already present on Twitch iirc. So in the endgame the only universal detection-proof solution I can imagine is AI/GPU based adblocker that will visually detect ads on your screen and overwrite them with something else without actually skipping.
