Whether you refer to online maps occasionally or on a daily basis, you can add several extensions to your Firefox browser to make Web-based mapping services even more useful.

Mini Map Sidebar is a suite of maps and tools that lives in your browser's sidebar. It offers integration with Google, Yahoo!, and Windows Live Local mapping sites, as well as Google Earth and GoogleSightseeing.com. Drag and drop addresses or enter geographical coordinates manually, choose from three displays options -- map, satellite, and hybrid -- then pan and zoom to get just the view you want.
