I like this add-on for several reasons. It does not just provide a single cryptic definition of a word, but rather opens The Free Dictionary web page for that word. You then have access to all of the information for that word.

Also, you have immediate and direct access to the Thesaurus. Since it is activated by double clicking a word, you do have to be careful with those double clicks.

I have found this dictionary to be very helpful on many occasions.

The new option for "Open on double click" is what I was waiting for a while now!

Those looking for a small bubble won't find it here unless the developer adds it. However, it is very comprehensive, fast, and a pleasure to use.

5 stars for the Chrome version, 3 stars for Firefox. In Chrome, the definition appears above the queried word. In Firefox, double-clicking a word to get the definition sweeps you away to a brand new tab showing the word's definition on thefreedictionary.com, which is very disruptive. Perhaps I'm missing something. If I find a solution, I'll edit this.

love it
