From the page Mozilla Labs » Blog Archive » Introducing Ubiquity:
You're writing an email to invite a friend to meet at a local San Francisco restaurant that neither of you has been to. You'd like to include a map. Today, this involves the disjointed tasks of message composition on a web-mail service, mapping the address on a map site, searching for reviews on the restaurant on a search engine, and finally copying all links into the message being composed. This familiar sequence is an awful lot of clicking, typing, searching, copying, and pasting in order to do a very simple task. And you haven't even really sent a map or useful reviews—only links to them.
Ubiquity is a firefox extension.
