You can solve the shortcut issue by installing the extension keyconfig from http://mozilla.dorando.at/

I have changed my shortcut from D to Ctrl+Alt+D, and now it works.

I would agree, though, that the interface could be better - it is not optimal to open an entire new tab to get one word translated.
