It seems the ###ad-west rule in both Easylist and Fanboy's list is partially hiding the news nav bar for the news items on the Yahoo homepage. This rule is probably not needed anymore since Yahoo recently updated their homepage. Here's a picture of it happening...
I've disabled the rule in Firefox however I can't in Google Chrome.

We have already removed that rule from EasyList yesterday, update your subscriptions.

And it looks like Yahoo is using ad-west again forcing me to block it now and breaking the news nav bar. Cursed Yahoo!
