This adblocking utility is both comprehensive and completely customizable - there's a way to configure literally any aspect of it that you want.

On top of blocking ads, and popups, the default Ublock also blocks sites that are known to be malicious or sites that impersonate others. On top of this, it seems to have found a way to get around adblocker detectors. Even if you don't mind website ads, you should still get this extension - at this point, it's a security requirement.
