I am using an iMac, MAC OS Sierra 10.12.4, Safari 10.1. MSN.com is my home page and I consider it to be horrible but I am not sure what else to use. For Safari I use Adblock Plus 1.12.4, Adblock 2.62.0 and Ghostery 5.4.10. Until just a few days ago this setup was working fine as far as blocking ads. A few days ago this changed. The MSN.com home page seems to ad free but when I link to any news article or other type of page it seems like the ad blockers quit working altogether. This seems to be happening only in Safari. When I use Firefox the ad blockers seem to be working fine. I know there are many software components to this problem and I am wondering if anyone has ideas as to what caused this happen so suddenly I will appreciate your thoughts.
