AdBlock Plus sold out. Google's Sponsored features continue to be automatically white-listed as part of that deal, even when "acceptable ads" is not selected. You can't block them using Element Hiding Helper.
Not ads - Sponsored listings. A good example is the YouTube video feed; the first video is usually a Sponsored video. I wouldn't care so much except they're usually link bait videos with hot girls or people getting hurt in "funny" ways. Don't want.
EasyList and other filter sets work on most AdBlock versions. I also use the social filters to speed up page load since most pages are waiting on Facebook, Pinterest, Twitter, etc auth & cookies before they can finish displaying.
AdBlock Edge is the only true ad blocker:
