Instantly Locate Yourself on Google Maps Firefox with Greasemonkey (All platforms): The Google Maps & Geode Greasemonkey user script adds a small Current Position link next to the Google Maps search box that instantly locates you on a map using Firefox's new geolocation technology. To use this script right now, you'll need to install the previously mentioned Geode Firefox extension—but as soon as Greasemonkey supports Firefox 3.1, which itself supports geolocation natively, you won't need any extra extensions. Since so many Google Maps searches start at your current location, whether you're getting directions or looking for nearby businesses, this quick link cuts out the work of entering in your address each time. Handy!
