I was sick and tired of watching the ever increasing ads on Youtube and added this to mozilla. It works. It really does work. It says that it blocked 3 my first video and It went straight to the content that I wanted.

I have since tried it on multiple videos. I guess I am in the youtube music DJ mode right now. I haven't seen an ad in the 30 mins I have had it. Awesome to the max.

I like this. It works good as mentioned.
