Recently at the right hand side of my FB home page (what used to be called newsfeed) I have been getting a column of small ads. Sometimes these appear to be linked to my personal data or interests as they appear on FB, and sometimes they include pages my friends have “liked”. However, they were not there before and I want to get rid of them! I use Flashkiller, on the latest Firefox browser, and Adblock Plus, which has always been excellent and I get no advertising on any other site I visit. I have looked at my FB privacy and security settings and can’t see (an obvious) way to clear these ads and stop them appearing. I am sure I am missing something as they were not appearing before!! Thank you for your help.
