Want to add an automatic map lookup to any web page that includes an address? Just install Greasemap, a Greasemonkey script that automatically scans any page you view for geotags, and if it finds any, inserts an iframe containing appropriate maps, courtesy of (you guessed it) Google Maps. Some users have reported somewhat sluggish performance, but if you've got a relatively speedy processor, plenty of RAM and a broadband link, Greasemap could help you save some steps when looking up addresses.
