I just love this. Granted once in a while i come across a word it isn't familiar with, but that is rare. Also it pops up at times i'm right clicking for another reason, but that too is rare. It is simple to use and i love the pronunciation option to actually hear how the word is pronounced.

Works well, but has a thin vocabulary.

Fantastic! Excellent add-on.

It only shows "No definition found" now

What happened? It used to work mostly fine. It does not recognize any word now

Great addon. It saved much time for me.

It takes long to search

Need an option to DISABLE on certain URLS! Driving me nuts trying to edit text and double clicking text makes this pop up instead of edit the text box.

A very good one, with the exception of a few disadvantages like limited vocabulary

It has become an integrated part of my browsing experience. English is my 2nd language. It is a strange experience to be without it.

It does not show up in my extension bar in Firefox. I had dig it out from withing the extension-menu. Took me a while to remember where this awesome add-on originates from.
