Mozilla Labs releases the Ubiquity add-on for Firefox. In a nutshell: With search, users type what they want to find. With Ubiquity, they type what they want to do.
Big congrats to Aza and everyone else who worked on this! As innovative as Humanized was, building something similar into Firefox is genius. Personally I am excited by the prospect of developing work flows on the Ubiquity platform. There are so many common work flows that need simplification.
