I'm very pleased to have this translator back—love that the panel at the bottom stays open, that I can click on the text that I want translated and that it automatically translates without additional clicks, that the original and translated texts remain open in the bottom panel, and that I can type in additional words that I want translated in that same bottom panel.

No extra clicks, translation stays visible. It's the best translator to help me learn other languages. Thank you for bringing it back. (I just hope this version is safe and conforms to Firefox's security mandates. As I understand, previous versions had been pulled for not adhering to requirements.)
