Wolfram Alpha search is amazing. I find it extremely helpful, and I am glad that the Firefox extension is already here. WAlpha is useful if you want to know, for example, the distance between New York and Cincinnati, without having to type the question into Google. I find it very efficient, and having the Firefox extension makes it even more effective.
