best ad blocker out there

Realmente eficaz, el problema viene cuando los sites que visitas bloquean el contenido al ver que UBO está instalado en el navegador.

the best adblock ever

Blocks lots of things, configurable (maybe too much :p), very rewarding. The recent downvotes about additional permissions to acces IP and hostname are just bad wording on the Firefox permission popup, and there's already a Firefox bug open about this, see https://github.com/gorhill/uBlock/wiki/Permissions#access-ip-address-and-hostname-information . So plese stop downvoting this excellent softawre for no real reason.
