2. Similarly, to remove the news ticker of your friends' latest actions, go to the upper right-hand side of the page, mouse over the little up arrow, then click "Hide ticker." Click "Show Ticker" to turn it back on.

3. To disable sound notifications, click the gear on the top right on the page and select Account Settings. On the page that opens, select Notifications in the left-hand column, and under "How You Get Notifications," click "On Facebook." Uncheck the box "Play a sound when each new notification is received," then click "Save Changes."
