I compared this content blocker, Handblocker, with two others: Content Blocker+ and Ad Block Multi. I opened a clickbait article on Facebook (Oola, Diply, etc) like "25 people share the moment they realized they wanted to run away and hide because they went into public with no pants on" where each story is on its own page plastered with 30 ads, and tested each of the blockers, one at a time. Results: - Ad Blocker Multi blocked NOTHING - same as no blocker at all - Content Blocker+ and Handblock: both pretty good. Blocked all the ads scattered within the story content I came to see. Block lists and advertisers change over time. I tested these blockers on March 4, 2017.
