That's correct.

However, there is a caveat here. Applications on your system can check your
MAC address and submit them (for example, Google Play's Music manager does
exactly this -
https://www.bentasker.co.uk/blog/general/292-virtualisation-google-play-music-manager-cannot-identify-your-computer
). So, if you're running the Facebook app on a tablet (for example) this
might be a concern, though at that point there's a whole host of other
identifiers the app could (and might) also grab to identify the hardware.

AFAIK, though, it's not possible to do it in Javascript (ignoring IE and
ActiveX calls) so it _shouldn't_ be a concern when hitting Facebook in a
browser.

Though you might still want to do it for the reasons related to it being a
public place.
