Here's the thing: It does block ads, however, if my understanding is correct, if you let the site through, the site auto references to an "OK" list that does not revert back to the block setting next time you access the site. OK some might say I want that, others who may be searching or an occasional visitor, will NOT want that. The list is hard to access and difficult to process.

Bottom line for me this is this blocks all ads ONCE, after that you have to take the time to work it.

I am not a firefox or AdBlocker anything. Cheers!
