A unknown addon in firefox addon store with 4.5+ rating.
(From, most of the comments it’s seems like this addon is suspicious and don’t have enough proof or evidence to trust it with our data. So please everyone avoid using this addon. A better one is “UBLOCK ORIGIN”).
Why not DNS level AdBlock?
I hope dns level blocking is less effective that browser level. Also dns level blocking cant apply cosmetic filters and give a clean view of webpages.
