How to hide Facebook Sidebar?

Here’s how you do it.

• First, if you have the Facebook chat sidebar open, go ahead and click the “Hide Sidebar” button in the bottom-right corner of the screen. When you do, the ticker will pop into a column to the right of your news feed.
• Next, look for the little arrow at the top of the ticker; hover your mouse over the arrow, and a little pop-up reading “Hide Sidebar” will appear.
• Go ahead and click the arrow. The ticker will disappear—and it should stay disappeared, even when you return to Facebook in the future.
• Want the sidebar back? Just click the arrow again.
