First of all, is the new project of Mozilla labs called Ubiquity.
Ubiquity is a plugin to Mozilla Firefox that allows you to communicate more easily with your online world.
How is that? Basically, you just open up a control panel by pressing "Ctrl + Space", and you can type intuitively anything you want, and ubiquity will try to make it happen.
For instance, I want to email my friend the map to get to the Empire State Building: Well I can't really add the google map to my email, the only thing I can really do is finding the map on google map and copy the address in the email. But what Ubiquity allows me to do is to actually embed the Google Map into my email along with other stuff like ratings of the restaurant etc...
Anyways, enough talking, just check this out:
