Does Adblock Plus block ads or hide them?

Just curious. I was looking at the Adguard Chrome extension and learned it does not block ads, it hides ads. I looked around for a definitive answer about Adblock Plus but couldn't find any.

 

Both. It has filters to block before a request is made, and then more filters to hide whatever was not block at request time. I do have benchmarks which measure what is blocked at request time: https://github.com/gorhill/httpswit...d-blockers:-Top-15-Most-Popular-News-Websites.
