Answer 1

heres the javascript i used for my site which works on every browser i can find in the office.

if (navigator.geolocation) {
                    navigator.geolocation.getCurrentPosition(function (position) {
                        latitude = position.coords.latitude;
                        longitude = position.coords.longitude;
                        //call your function that responds to lat & long
                    }, // next function is the error callback
                        function (error) {
                            switch (error.code) {
                                case error.TIMEOUT:
                                    alert("Timeout");
                                    break;
                                case error.POSITION_UNAVAILABLE:

                                    alert("Position unavailable");
                                    break;
                                case error.PERMISSION_DENIED:

                                    alert("Permission denied");
                                    break;
                                case error.UNKNOWN_ERROR:

                                     alert("Unknown error");
                                    break;
                            }
                        }
                        );
                }

With the error checking in that code you should be able to diagnose what the error is from there.
