Another Great Chrome Extension: Dictionary!

I know many of you may not use Chrome, but I am sure this extension or a similar extension is available in Firefox and maybe even Explorer. I downloaded it and it now appears up in the corner of my screen when I am on the internet. If I get to a word that I do not know, I just highlight the word and click on the dictionary and I get all sorts of definitions and even the verbal pronounciation in some cases. I love this web extension and would love to see it on every student computer so that they could learn words as they read them on the screen. It goes great with my "text to speech" Chrome extension as well! Thanks to Richard Byrne and his Free Technology for Teachers blog for helping me find out about this extension!
