It launches it in app mode (no tabs, no URL bar). I'm not sure if that's the same thing as launching the FB app. In windows you copy the chrome shortcut and then edit the shortcut to add the command-line arguments. Then you add the shortcut to your launcher bar. Alternatively, you could create a batch file for each site that you want to isolate somewhere in PATH and launch it from the Start -> Run menu. In other words, you'd press the start key, then type "facebook", then press enter. (Please correct me if my instructions are incorrect, I haven't used windows regularly for a long time.)
