As sesqu said, this features is built into firefox. I only have a window-wide url bar on my firefox and extensively use these "keyworded" bookmarks.

So in my url bar I can "g foo" to search "foo" using google, "wp foo" for wikipedia fr, "wpe foo" for wikipedia english, "imdb foo" for imdb, "yt foo" for youtube, "dm foo" for dailymotion, "gdv foo" to load the document which url is "foo" into google docs viewer, "tw" take me to twitter, "fb" to facebook, "hn" to Hacker News, "mail" to gmail, "reader" to google reader, "in" to linked in... I don't have to all list in my head, it's mostly a finger habits now.

What is really cool since firefox has the awesomebar is that it is aware of this and display the actual url so when i type "imdb foo bar" i see "http://www.imdb.com/find?s=all&q=foo+bar at the top of the proposed url.

This is really handy for people like me who mostly use their keyboard: this powerful firefox feature is just a ctrl+L away when I'm already in firefox :-).
