The auto-refreshing status ticker in the sidebar of the new Facebook layout is distracting. How do I remove it?
Facebook doesn't allow you to disable the ticker - it only allows you to make it smaller:
You can't close ticker, but you can make it smaller by moving the horizontal bar between ticker and chat. Slide the bar up to hide ticker and make your chat list longer. Pull the bar down to show more of the ticker and hide chat.

However, you can install a Greasemonkey script, or Chrome extension to hide it:
UPDATED: As per Kered Negah's answer below, Facebook have implemented a Hide Ticker / Show Ticker function. Fantastic!
If you have an ad-blocking extension, you can add these to the manually edited list:
Works equally well in Firefox and Chrome.
This other Chrome extension (aptly named Unannoying Facebook) does this for you, and also removes the hovering bar on the top, if that bothers you for some reason.
