It works. It always works. Excellent selection of filter subscriptions and defaults work excellently if you do not know what to do with the other options.

This add-on is free. While they offer a paid premium flavor, they do not ruin the user experience with intrusive up-sell messages.

Considering all of the other ad blockers that I have tried through the years, Adguard is my favorite.

Note that there is an iOS flavor which works just as well. I am sure if they have an Android option it would be equally great.
