I am seeing ads after having this add-on for years.

Excelente aplicación para bloquear anuncios

its very good

exellente extension de navigateur bloquant toutes les pubs (Près de 900 éléments bloqués en une journée tout en restant sur youtube)

Muy bueno para bloquear esos anuncios intrusivos y llenos de malware.

Excellent in removing annoying and obscene ads.

This add-on works great just as it says. The only thing I wish they would add is a way to quickly add it to my filter list instead of having to open the add-ons preferences and physically adding the the site in question.
