If after a while you feel that you want it back, just click the chat bar in the bottom-right of the screen or in the wide large screen, click the button on the left sidebar under the Marketplace link (see second and third image below). I guess that after hearing a lot of user complaints, seeing many unofficial “apps” for different web browsers that came out trying to help getting rid of the sidebar, and other work-around that were popping up on the web. Facebook finally realize that they were doing more bad than good, and in many cases they weren’t enhancing the user experience with the always-on sidebar — now is lesson learned!         It still a little bit uncomfortable that there are two ways to show the sidebar back, but at least you won’t be bothered as much anymore. Be the first and tell us if you like or not the new Facebook sidebar. All content on this site is provided with no warranties, express or implied. Use any information at your own risk.
