Forum Change Background Hover Colour Behind 'Notifications'
 

When I hover over 'Notifications' in the toplinks of my forums, there is a blue background that appears. I have looked everywhere, tried finding it in Firefox, everything and I still can't work out how to remove this hover background.

I still fail to understand why StyleVars was introduced, it's by far the dumbest inclusion in a vBulletin release to date.
