I think the only way to prevent that would be to allow the ads. And then push them out of view or maybe make them invisible.</P> Sun, 26 Feb 2023 19:16:24 GMT jscher2000 2023-02-26T19:16:24Z https://connect.mozilla.org/t5/discussions/browser-sniffing-capability-for-ad-blocking/m-p/25888#M10422 <P>So, very recently, I've noticed that certain websites like "The Weather Channel" and even "WeatherBug" are somehow doing some browser-sniffing? to find out if you've got 'Ad-Blocking' set in FireFox.&nbsp; And, if you do, some sites are now denying you access.&nbsp; The Weather Channel does this now.&nbsp; It won't let you use the site, unless you turn off Ad-Blocking.&nbsp; WeatherBug is a little bit nicer about it.&nbsp; They just ask you to consider turning off Ad-Blocking, but they still let you click through the pop-up banner and use the site...</P><P>It might be nice if Mozilla could eliminate their ability to detect if we have Ad-Blocking turned on.</P><P>&nbsp;</P> Sun, 26 Feb 2023 17:10:51 GMT https://connect.mozilla.org/t5/discussions/browser-sniffing-capability-for-ad-blocking/m-p/25888#M10422 GRR 2023-02-26T17:10:51Z https://connect.mozilla.org/t5/discussions/browser-sniffing-capability-for-ad-blocking/m-p/25902#M10427 <P>A common method of detecting whether ads are blocked is trying to load ads and then if they don't load, assuming they were blocked.
