Filtra la mayoría de ads que encuentro, son puntuales los casos en los que me ha fallado. Recomendada.

This blocker will sell data to companies, as has been proven in the past. The trackers it has "whitelisted" are also sketchy.

I use this add-on in conjunction with Firefox's "Strict" setting in the Enhanced Tracking Protection on the Privacy & Security settings page. It works!

Nasty app...
