It is not efficient. Have you ever learn any user experience? such annoying experience as ad. I dont recommend.

very very efficient

This outfit is a fraudulent advertiser. It advertises its software for $2.50 one year for the holidays but it charges your credit card for $32.05. I could not find a US vendor, just a Bulgarian address. I am not wasting more money calling that.
Its final charge is average for a small software but what is dishonest is the bait & switch…and since they are in Bulgaria the only way to protect your card is to cancel and get a new one, which is a wrong time of year for that…and I suspect that they anticipated that too.
DO NOT PURCHASE THIS AD BLOCKER online, it is a crock.

Gran experiencia, no es molesto y su desempeño no afecta la nevagación, sin duda un excelente trabajo de los desarrolladores, muy recomendable

Recommended by Firefox meaning you can be a little more sure that what you type and the pages you are looking at are not being snooped on.

Other than it does everything it says on the tin that's written on their "About this extension" and it a lot less clunky than the other adblockers.

My only critisicm is that it would be nice to disable to automatic application of adblockers or at least flag specific ones to not enable again after the fact. I use this on a work PC and some of my customers are foreign and so it picks up on the foreign words and then applies that filter. It says that having too many filters can affect performance so since I don't go on German (for example) websites I don't need the german filter but it keeps applying.
