I've got it configured so that it's showing the sidebar, but the menu thinks it's not: http://cl.ly/image/3032413v1d3W
Anything odd about this particular window? Did this occur after a session restore or other restart? Did you toggle prefs manually in about:config in this session? Have you enabled/disable social using the menu item in that session? We need more detail about what could have happened to cause this, so any extra information you can recall/provide would be useful.
