Now granted, most of these will need additional configuration once installed to be effective. Downside is that you need good security knowledge to configure some of these settings. Most can be rather obvious, but some can trip up those without deep knowledge.
For example, Referer Control is particularly subtle, as its only mod requires you to set the referrer to be [], and (if it is disabled) to have JS referrer handling active as well.








The requirement for this is that those extensions need to directly interact with - and respond to - page elements.
Security add-ins are a “black hole” in that the vast majority of them only block, they don’t interact. There is absolutely no way for a website to tell which ad-blocker is installed from purely the ad-blocking component itself. Provided the add-on is constructed properly, it should never respond to any code either on the client-side or server-side, it should only block the browser from not even requesting certain assets in the first place. In fact, a good adblocker should be indistinguishable from a failure of DNS in providing the IP address of the ad server.
