I’m going to talk about a few Firefox extensions that I find very useful and intriguing. The first comes from Mozilla Labs: Ubiquity.
* Lets you map and insert maps anywhere; translate on-page; search amazon, google, wikipedia, yahoo, youtube, etc.; digg and twitter; lookup and insert yelp review; get the weather; syntax highlight any code you find; and a lot more. Ubiquity â€œcommand listâ€ to see them all.
* Find and install new commands to extend your browserâ€™s vocabulary through a simple subscription mechanism
* Read about Ubiquity In Depth, or see a number of the commands in action (with screenshots) in the Ubiquity Tutorial.
It’s awesome! See the video presentation from Aza Raskin
