Adblock Plus

So I've been trying to use a blacklist approach to using ad block. I was told how to successfully block ads on devientart and now I want to block ads on wikia because they apparently have too many heavy ads for their own good. (makes scrolling through long wiki pages on there a pain.) I tried using the same method I was told for blocking devientart but it doesn't seem to be working. ABP is indicating it is not turning on.

Here is the line I tried to add, also tried to add it to a separate custom filter list: I'm guessing I need to use another method for blocking ads on wikia. So any help with this would be great.

you can't use separate filters
you have to use only 1 filter for your blacklist add all other sites you want in the filter above

Thanks, I had a feeling it was just a case of me not knowing how these custom filters work. Well, at least now I know how to add to my blacklist when the need arises. (By the way, Wikia is alot more usable with ABP on. )

Thanks again for your help!
