Firefox has already integrated the geolocation feature, which enables websites to get geographical information of users and serve content accordingly. This technology depends upon the user’s IP address, and hence generally it fails to detect the correct geographical location of the users. 
Thankfully, You can set your latitude and longitude manually in Firefox! To change your geolocation information, follow these steps:
- Find your exact latitude and longitude. (check this tutorial at Lifehacker to find your latitude and longitude)
- Type about:config in the address bar and click on the “I’ll careful, I promise!” button.
- Type geo.wifi.uri in the filter box.
- Right click, and modify it to the following value:
http://snaptome.appspot.com/loc/json?latitude=your_lat&longitude=your_lon&accuracy=10
Change your_lat and your_lon to your latitude and longitude. Now, you can check correctness here. Thanks Doug Turner for the tip.

How do you format the degrees minutes seconds N (W)?
This didn’t work for me. What did work, and doesn’t rely on the continued functionality of snaptome, was following the advice at http://blargasm.com/post/7979697232/firefox-geolocation. It involves pointing geo.wifi.url to a local file that has specifies the location in the correct format. It looks like the following (to steal blargasm’s example):
{“location”:{“latitude”:50.941863,”longitude”:6.958374, “accuracy”:20.0}}
