There's an easy but convoluted way to add keyword shortcuts to Mozilla's URL address bar. A convenient one to add enables searches with a search engine of your choice (Google, for example). Note that you can also set the search preference through the Prefs fields, but this method saves a keystroke or two.
First, you need to open Mozilla's preferences. Go to the Navigator -> Smart Browsing section and check the "Enable Internet Keywords" checkbox and hit OK.
Create a new bookmark (any page; it doesn't matter which one), and open the Bookmark Manager (command-B). Right- or control-click on the new bookmark and choose the "Properties" option in the popup contextual menu.
In the new window, with the "Info" tab in front, rename the bookmark as Google Search or something, and for the location, delete what's there and paste:
http://www.google.com/search?hl=en&q=%s&btnG=Google+SearchFor the Keyword, put something that you want to use to preceed your searches; I use "?". Description doesn't matter. Now hit OK, and you should be groovin'. Go ahead and search Google using the new shortcut -- type "? search_term" and hit enter, and you should hop right to the results page for "search_term".
