You're probably being "fed" ads tailored specifically to your personal preferences, based upon your browsing history.
Regards,
You're right! I decided to do a test. In this original story at the Post, there was an ad with pictures of a prostate and "Do this immediately if you have prostatic," which is why I asked the question on this thread. So, I copied the link of the article and opened in a Firefox private window and that ad was gone as well as a whole lot of other junk. Thank you very much! I'm going private window from now on.
