Geolocation API Blocker

The Geolocation API, a standard feature supported in all major Web browsers, allows sites to infer your precise location. Past research has shown that many sites using this API do not require an extremely accurate location to function correctly. Yet, there is no native way to make the reported data less accurate.

Geolocation API Blocker is an open-source extension that allows the user to modify their reported coordinates for different hostnames in two ways:
1) A fixed location of their choosing.
2) A noisy location uniformly distributed inside a circle of specified radius centered around the actual location.

The extension only works with the Geolocation API. It cannot protect against methods that use your IP address.
