Works MUCH better than Dictionary Anywhere, (which doesn't work at all), I can tell you that. It takes you to a different page but it works. The redirect is likely why this add on isn't more popular.

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 am going to save myself some typing by copying and pasting the 3-star review by active x:

"Great! It just works. However, I had to uninstall it because the 'double-click to lookup' feature cannot be disabled. I don't like it that it immediately works on my selected text when I would often be just double-clicking to select text to copy it.

"There's another extension named 'TheFreeDictionary.com Lookup' that works just like that. I was hoping to use the official one for being more trustworthy."

I agree, word for word, including recommending that other extension. Why? Because that one works just as well but allows one to use the right-click context menu instead.

Very short-sighted of Farlex to assume that one would only double-click a word or phrase on a web page for the purpose of looking it up on TFD. And, I mean every time, no exceptions, no options. This would have driven me nuts.

I am not as charitable as active x, however. Only two stars from me; it would have been one if I did not value TFD as highly as I do otherwise.

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.

it works. but opens the website in new tab. not floating or bubble up window instead.

It sweeps me away from the page I am looking up the word in question. It could be a pop-up just above or beneath the word.

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
