Ubiquity: The Next Big Thing

This is the most impressive browser extension I have seen yet: Ubiquity.

It’s a mixture of Quicksilver and Yubnub combined with functionality similar to Greasemonkey integrated tightly with Firefox as an extension for doing stuff and creating mashups. I think this could quickly become the main reason to use Firefox over any other browser. Maybe not for every user, but certainly for technical users and effeciency nuts (like me :))
