Works great, but if you start looking up words without selecting the language, it looks like an English dictionary. The screen that talks about a $15 upgrade is a little confusing. This Firefox sidebar already has all the features that cost $15 on IE.
This is an English-only dictionary. While perhaps good for that, it does not do translations as claimed, which is what I searched for. That requires the separate $15 product. I do not like bait-and-switch.
so far so good I really like the pop up it is so much better than opening a new tab for the reference button on yahoo. It actually give definitions not to be sarcastic or any thing about the reference it is to the point without all the other junk. Nicely done
