WAlpha is Extremely Useful Rated 5 out of 5 stars
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.
Simple Yet Powerful Rated 5 out of 5 stars
WikiLook is an amazing tool. Now, searching m-w.com for definitions is nearly as obsolete as searching for the word in a paper-based dictionary. The definition boxes load fast and they don't get in the way, as you can get rid of them as soon as you're done. The best part is being able to find words in other languages. In short, WikiLook is a simple and easy to use tool, yet it is extremely powerful and highly useful, especially for productivity freaks like me.
The only additional feature that I would like to see perhaps is a pronunciation guide for the words (IPA)
