Me ha ayudado a bloquear anuncios que otras extensiones para el mismo fin ya no bloqueaban.

Does what is says--blocks ads on websites that annoy or try to grab my attention, annoying. :)

re rapido y efisciente.

Very good

slows loading websites, but delivers what it promises

Really nice Extension for block ad

AdBlocker Ultimate works like a Dream!!!

Doesn't do anything to stop youtube ads.
