DeepL is my translator of choice. It is usually very accurate—but for official work (as with all translator software), I follow up by reverse-translating. This ensures my meaning has been conveyed as precisely as possible. If in doubt, I review the input text and punctuation until satisfied. I like this software a lot, and recommend it to others.

Greate Extension

Das überraschendste Add-on diesen Jahres: Faszinierend, wie komfortabel ganze Websites oder einzelne Passagen übersetzt werden! Eine Fremde Sprache ist jetzt kein Hindernis mehr. Für mich jetzt noch mehr der beste Übersetzer im Internet!

SUPER!

Funktioniert einwandfrei.

awesome!

Same bug: on sites where there is text input in the form (for example github), after entering text and scrolling down there is a ghost frame with text.

Super simple and effective!

Die mit Abstand besten Englisch-Deutsch (Web-Seiten) Übersetzungen.

I used to use the Google or Bing translator a lot, but since discovering DeepL Translate, I'm even happier to translate foreign languages well. It's great when integrated into Firefox with this free Add-on.

Very bad

Fantastic service and extension!

Overall, this add-on is great, though it has some room for improvement, here are some suggestions:
An option to display the translation pop-up immediately upon text selection.
The audio to help pronunciation is good, but the TTS engine could be better(it's using speech synthesis capabilities provided by the operating system)
An option for a more minimalistic layout for the dictionary to avoid excessive scrolling.
