How does Facebook know my location?

And how do I permanently disable this?

In Safari on a MBP, btw.

It's a combination of your IP address as well as the locations you and your friends have given to Facebook voluntarily.

Via the ISP you chose to make a contract with. Maybe you can use one of the many of Proxy Servers out there to serve anonymously or Hotspot Shield.

So there's nothing on my actual system that they use for location data?

Not your personal data, unless you give Facebook access to it. It is just your IP address.

The closest they can get with your IP address is your city, or perhaps a general area of the city, and the name of your ISP. They can't see your street address. To see what it reveals, just go to this site: http://whatismyipaddress.com/

Yeah, all that ever pops up is the city.

Thanks for the link, haven't seen that one before.
