Script Summary: Hides the sponsored and annoying sections that you can't normally get rid of.
This script removes many of the annoying ads and updates that unavoidably appear on your Facebook pages. There are cleverer Facebook tidy scripts out there, but this one is nice and simple and possibly easier to update as new adverts come along. It's also very easy to customise, should you want some of the sections that are blocked here by default to actually appear.
NOTE: this script also currently suppresses the ability to use the /online friends/ box to initiate chats.
