Trying out AdBlock for Safari (Apple App Store—free) and so far, so good. Tried a few websites that were more ads than content and it seems to work as advertised. Hopefully this will reduce the ads sucking up bandwidth.
This site, www.w3schools.com is especially egregious and now that ads are just gone.
@feloneouscat I just started trying out Adblocker Ultimate on Chrome. I was shocked how much faster certain sites are now loading.
