Demo of Ubiquity for Firefox (by Aza Raskin)

Ubiquity adds intelligence to your browser… It is a Firefox plugin that interprets natural language, maps your commands to a webservice, serves your arguments to that webservice and inserts the results for you in your editing interface.

It runs a kind of macros, user-contributed snippets of javascript. It makes me think of the CoScripter project at IBM - see writeup by Jon Udell.
