"Mozilla has introduced an experimental Firefox browser add-on featuring powerful geolocation capabilities. Called Geode, the technology allows the location of Web surfers to be fixed and then maintained as users move about their hometowns, across the nation, or even when traveling around the world.

"You'll be able to play with this in the upcoming beta releases of Firefox 3.1," Geode's developers said. "We realized, though, that some of our Firefox 3 users might also want to get a head start playing with geolocation today, and users can tell us what they think of the experience it provides." "
