I use ghostery.
And it’s not the designers, it’s their management.
Web ads have been destined to fail. As this becomes more obvious, the management gets more desperate.

Essentially you change your routers choice of DNS to
Primary: 198.101.242.72
Secondary: 23.253.163.53
then on your home LAN these two addresses will be used rather than your cable default DNS. These unwanted sites will return 127.0.0.1 (a guess?) for annoying ad sites as well as malware & phishing sites. I had been using Ad Block Plus add on, but so far this seems to be better and faster..at least so far. It seems too good to be true...so keep alert. Perhaps some Freeper could explain the downside?
