Utter schite....get it off here!!

It is not blocking sponsored ads.

Doesnt work at all..

Doesn't work.

Worthless. Didn't block anything.

Lotto Lout ad is annoying me and this has not erased it. Recent ads have appeared that are making me think about leaving FB and a working blocker would be most welcome.

Didn't work on my system. It was updated on the same day it was installed. I rebooted the system, and still it didn't seem to work. I was really hoping it would work because these sponsored ads are annoying to see.

Doesn't work on Firefox 53
