Dave,

Some of your comments regarding Firefox are incorrect.

False.  Assuming the user isn't using gpsd, or any location add-on, we will continue to ask our location provider (GLS) for a location.  GLS may or may not return a location.  But typically they do return a location based on GeoIP.

I don't think I can make a blanket statement like that - it really depends on the platform.  The WiFi scanning code is different on each platform.  For example when using iwlib, I remember it only being able to return ap's when you were connect to one of them - or something like that.

> Firefox 3.6.8 also fails to make use of locally connected GPS devices.

Another false statement.  Since the middle of last year we have support any GPS device that exposes itself to the system using GPSD.  On Android and on Windows Mobile, we'd ask the system (which may or may not have a install GPS) for location information.


Regards,
Doug
