Why is the icon not the same color as the shield?

Doesn't block all ads. Specifically those I meant to block because they're loud and startle me. Also throws occasional ads in your face itself.

whats an ad?

One of the best adblockers

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.
