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 thatās 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.
The way youāve described it is basically how it would have to work.
Various ad-blocking detection technologies basically boil down to loading some element on the page and then querying for it during/after rendering to see if itās still there. This could be combined with an AJAX call to load the actual content, which is how all those annoying sites work that pop a nag up in your face if youāre running uBlock or whatever. And even then you donāt get the content even if you subsequently block the nag notice.
A truly undetectable adblocker would still have to pull down and load all the ad content and render it somewhere (invisibly in the background, presumably) and then serve a second cut down version of that page with the ad elements not rendered.
Edit to add: This would be somewhat detrimental to the user, because it would by necessity not stop the types of tracking that are typically built into served ads. Current adblockers (like uBlock Origin) also by default also block various advertisersā nonsense like cross-site tracking cookies and tracking pixels, etc.
