How to change the location setting of Firefox

Question

I want to change the location of our browser to the USA. Please help me change the location of Firefox, i.e. the location of the geolocation for testing.

Answer 1

The two preferences mentioned by nmaler are in place. In addition, you do not need a (local) server, data: -URI also works fine.

For example, if you set geo.wifi.uri(at about:config) to:

data:,{"location":{"lat":1.2,"lng":3.4},"accuracy":4000}

and then test by running the following from the JS console:

navigator.geolocation.getCurrentPosition(pos => console.log(pos.coords));

then you will see that the parody succeeded:

Coordinates { latitude: 1.3, longitude: 11, altitude: 0, accuracy: 4000, ... }

: -URL JavaScript (, ), . , encodeURIComponent , pos - , % # ( , , ):

var pos = {
    location: {
        lat: 1.2,
        lng: 3.4,
    },
    accuracy: 4000,
};
var geoWifiUrl = `data:,${encodeURIComponent(JSON.stringify(pos))}`;
// TODO: Set geo.wifi.url pref to geoWifiUrl.

- :

• ( ) geo.provider.testing, true. ( OS, ).
• geo.wifi.uri URI , . http://localhost:8888/
• Firefox.
• , ,

about:config prefs.js . - about:support.

python2 ( ):

import json
import BaseHTTPServer
import SocketServer

PORT = 8888
LAT, LNG = 38.894967, -77.034917


class GeoHandler(BaseHTTPServer.BaseHTTPRequestHandler):
    def do_GET(self):
        self.send_response(200)
        self.send_header("Content-type", "application/json")
        self.end_headers()
        self.wfile.write(json.dumps({
            "location": {
                "lat": LAT,
                "lng": LNG
            },
            "accuracy": 4000
            }))

    def do_POST(self):
        return self.do_GET()

httpd = SocketServer.TCPServer(("", PORT), GeoHandler)
print "serving at port

API HTML5, :

• about:config.
• geo.wifi.uri.

• - :

  data:application/json,{"location": {"lat": 40.7590, "lng": -73.9845}, "accuracy": 27000.0}
  

  ( lat lng .)

Please note that if you want to prevent sites from determining the location by your IP address, you cannot do this at the application level - the only way is to use a proxy.
