location tracking

[wi_badger]

....maybe I am being overly cautious,  but reading Mozilla's disclosures and disclaimers they use third parties and share
information with them including Google and others, But they tell you they are not responsible for what the third
parties do with that shared information.

I'm not sure that it's possible to be "overly" cautious about these issues ... but not surprised that they share information.

The key question is how much information is passed in addition to location.
IP address, almost certainly, MAC address maybe.  Phone number ?   Don't know.
Name ?  Lots of us out there named mobian, right ?  But how about the name on an email account ?    Again, don't know.
