Google Maps and other mapping services are among the most useful sites on the Internet. But they have one shortcoming: you have to visit them to get their information. Wouldn't it be nice if you could get mapping information no matter where you were on the Web?
That's what the Mini Map Sidebar does. Open it as a Firefox sidebar, then drag and drop address names or links to it, and a map of them will open right in the sidebar. You have your choice of map services including Google Maps, Yahoo Maps, and others. You can then zoom in or out, get directions--pretty much anything you can do on the mapping site itself. In fact, you can even do more because Mini Map Sidebar includes some nice extras such as traffic information.
Note: This link takes you to the vendor's site, where you can automatically install the file into your Firefox browser.
