User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:17.0) Gecko/17.0 Firefox/17.0 Build ID: 20121119183901 Steps to reproduce: I enabled social.enable and social.active. I then right clicked on the menu bar and chose Customize. I tried moving the four Facebook buttons to my other buttons, which are located between "Help" and the Awesome bar (in the topmost bar, above the tabs). Moving the buttons next to the tabs also does not work. Actual results: The buttons cannot be moved, although a black line indicating the target of my move is shown. I guess they can only exist in the navigation toolbar. Expected results: The buttons should be moved whereever I want them to be. It would also be very nice to be able to move the four buttons individually.
