Was moving out of chrome for the good firefox offers and was terribly missing the 'google dictionary' extension. Thanks a 3000 for this add-on.

Dev, I don't know who you are but I love you...

...for this addon.

Edit:

A couple of things.
When double clicking a word in the popup, search that word too.
For some reason, it fails on the word "rapidly".

Excellent! The only criticism would be the "Searching... Please wait." screen. The lag is undesirable and could be worked on, but showing a "searching" screen makes it worse than it would look without such a note.

Really nice extension. Does what it is made for perfectly. It is exactly what i needed.

I always had to switch to chrome because of the google dictionary extension. Guess what? I don't have to rely on chrome anymore, thanks to the developer.

Simple and effective. Thank you!

Just a question: a previous reviewer mentioned that it was necessary to define "dom.webcomponents.shadowdom.enabled" as true in about:config... I'd like to know more about this, since the plug-in works well even without that property being set.

Just what I was looking for. Quick pop up dictionary with short definition.

Works exactly like the google dictionary on chrome. Simple and fast. This should be checked and recommended by firefox team.

The very best addon for dictionay: I've asked a feature to the developer and he understood and found an even better solution. Be aware of privacy if you use other addons doing similar things: this addon take care of your privacy by letting you ask for a definition only if you want (the Trigger key you need to press to get the definition: I love the Shift one).
Many thans to the developer!
