Appeared "broken" after a recent update, but this solved it: Click AdBlocker icon on Firefox header, click on "Settings", and click the Refresh icon (top right corner).

Great extension. I especially love the element zapper. Makes the already uncluttered website even more readable. I would have gone mad from the ads without it. Great work!!! You guys along with all the other ad blockers are the true guardians of the internet.

This is an all around awesome extension. :D

amazing stops most ads, allways update

talking about plug and play. instantly took all the annoying garbage away.
thanx
