I then added the keyword
map for this bookmark, and can simply type "map " in Firefox's address bar to see the location in Google Maps.
[EDIT] Lifehacker has an article on Firefox quick searches complete with a set of bookmarks which includes a Google Maps shortcut.
Also, after some testing, I find the following simpler Location also works:
