You likely have a ad blocker, as I do, but I just checked Fox News and there were over 250 network requests (open page, then in Firefox hit F12 key and then Network then F5 then see Requests on bottom left) in about a minute. FR: 4.
Not sure of purpose of your comment. I did not argue that sites aren’t attempting to show popups or other ads; simply stated that I didn’t see any. Brave Shields in standard mode shows 38 ads blocked on Fox News front page.
