The best.

Muito bom bloqueia muitos anúncios assistir o youtube fica muito mais agradável

This is so easy to install and works exactly as described. Highly recommend.

Maravilhoso!

I thought it's just "to good to be true, click-bait" when I saw that Youtube adds are also blocked. I haven't seen an add since I got AdBlocker Ultimate. Thanks to the developers, you guys are doing a GREAT!!! job!
