Awesome script. This script alone is enough reason to use greasemonkey.

Easily one of the best scripts here. Huge amount of customizability, very easy to understand. The simplest of interfaces. Very thorough supporting documentation. If only every script on userscripts.org were like this one.

And that's not even getting into the functionality. It's designed as a dictionary aid but it has potential for so much more. I can see this easily replacing Firefox's built-in search engine box. Use it for google, yahoo, whatever you want. With a few clicks I added ebay, the Weather Network, and even the firefox addon search engine.

Great script, just fantastic. Can't give it enough stars.

this is my absolute favorite script. i use it all the time to look up words in wikipedia, wiktionary, or google without leaving the article and disrupting my reading pace.
