Mapz: A GIS Librarian provides a listing of mapping extensions for use with, you guessed it, the Firefox 2.0 browser (you are using Firefox instead of IE, right?). There are 16 of them listed, which you can download individually or as a package. The extensions include:

• Google/Yahoo!/Live Local et al Map Extensions
• Region Specific Extensions
• Geotags (Websites & Images)
• Track Packages
