If you have a new web browser that supports the W3C Geolocation API web standard, you will now see a My Location button on the left hand side under the street view button that will pin point your exact location on Google Maps. You will only notice this button if you have a Firefox 3.5 or a Google Chrome 2.0+ web browser.
So what does this do for me? It could worry you that their is now technology that can pin point your exact location from your very own home. On the positive side, if your travelling around and your a bit lost, you can now find where you are.
Once you click the button, you will be prompted to allow Google Maps to track your location. Google says that they take privacy very seriously.
Google takes privacy very seriously, so your location will never be used without your permission. The first time you use My Location on Google Maps, you’ll be asked to confirm that you’re happy to share your location with Google Maps, and you can always undo your decision.
So does this mean if you use the feature once, they can track you? You might want to read their privacy policy first.
