Facebook is quite nervous after the launch of Google+ and is releasing new updates after every few days. Recently Facebook has made few more changes to its design. Out of which two changes are annoying and are criticized by the users. These two changes are fixed top blue bar and real-time news ticker in the sidebar.
Real time news ticker shows the real-time updates of your friends in the sidebar. Whenever a friend of yours comments, like or uploads a new photo, a new update is shown in the news ticker. There is no official way to hide this new feature. However if you use Google chrome as your browser then you can turn these two features off.
Unannoying Facebook is a Chrome extension that removes the news ticker from sidebar and also removes the fixed top blue bar.
If you just want to remove the news ticker from sidebar and want to keep the new top blue bar then you can install Facebook News Ticker Remover extension.
