Once upon a time this was a great add-on. And then the developer got greedy and decided to create "acceptable ads." As hypocritical as this is, I can overlook it. However, the crap UI makes this extension a pain in the butt to actually use. I still can't find anything to show what can and can't be blocked anymore. You used to be able to click a button and pull that up. For the love of all things human, can you not design a decent UI and if you can't put the commands back in because of changes in Firefox (aka, Chrome 2), could you please include some text in the thing on how to find them.

Try Ublock Origins or any other fork. This one has jumped the shark.
