Great add-on. I can't understand why there's not other pop-up dictionaries. Believe me, I looked when I was having trouble with this one. Turns out, if you're using uBlock or some other blocker, you have to give new permissions to the new dictionary home page - (Dict.org). It was added with the latest release of this add-on (1.8.3). Also can't find a way to donate to this guy. I click the contribute link below and Paypal says "This recipient accepts PayPal payments only through their website." Ya gotta make it easy bro. Good work though.
