It's fast, simple, and practical for sure. It lacks privacy due to its Google use although you could try to use wordnik as a source as duckduckgo uses it.

Great addon! My only issue is that it doesn't work with Reader View. Would give 5 stars if it did. Cheers.

Almost perfect. There's one thing that's missing. I would love to have a little Dictionary Anywhere icon on the Firefox toolbar. So that I can search words that pop up in my mind but not necessarily on the site I'm in. Please add this feature. I literally have to go to Google Chrome for my reading and researching because you don't have this feature yet.

This works very nicely, thanks a lot! The only thing missing in my view is (as in the Chrome equivalent) an extra option to press a trigger key to "Display pop-up when I select a word or phrase". Basically, I want the double-click to immediately translate a word and "CTRL+highlight the text" to translate an entire phrase. Would that be possible?
