The ABSOLUTE best AdBlock extension out there! I've used it for almost eight years and I'm happy to see it's on Firefox.

O melhor da categoria! Só falta gravar os sites permitidos na nuvem, só isso!

Works amazingly on every browser (by which I mean chrome and firefox, cause blegh). I WILL pay you guys someday soon for this service after I get some financial stability, but until then keep it up, you folks are awesome!
