This extension solves many problems better than prior translators I've tried. It's very well integrated with the Firefox browser, and could hardly be easier to use. I deeply value the fact that the translation engine is executed locally to the machine, and *not* in a cloud where user data is aggregated. And the quality of machine translation that I see, is not significantly different than Google's service.

One possible improvement might be to allow the user to choose between alternate translations of phrases or sentences.

There are people who expect translations like Google's.
Google is a multi-billion dollar company that has the resources to create highly refined products in a short time. That's not to say that doing a translator takes little time, let alone that it's easy.
However I quote a question from a user who gave a star, why does that happen?

"Questions : Why does 'Firefox Translations' connect to [o1069899.ingest.sentry.io] AND TO [incoming.telemetry.mozilla.org] AND TO [storage.googleapis.com], to the latter in particular? What privacy when a Google server is aware that user lambda is calling it?"

Great extension. Has a better interface than all the other options, and translates entire pages better than the other extensions. Like the feature where it can underline words that it may have translated incorrectly. Also very fast compared to others.

Just wish it had more languages like Greek or Chinese.

Fast and useful :) I hope next version has an option to specify formal/informal in German.
