Advertising » Ads on Yahoo not being blocked

Hello,

Recently having some trouble when I go to yahoo.com. I read through the news headlines and every few headlines there is an ad there. If I right click on it I don't see an option to block those ads. Can anyone help me figure out why they aren't being blocked and what I can do. It's a bit annoying to be reading a news headline and then realize it's a advertisement.
Problem is right at www.yahoo.com
I am on firefox 20.0.1 and Adblock Plus 2.2.3. I am subscribed to fanboy's adblock list and I did manually update the filters just today (and then I restarted firefox) if that matters at all.

Any help will be apprecited.
I didn't find the right solution from the Internet.
