Unluckily since today it is not working anymore (Firefox 136.0.3). I am getting "Error: Unknown Error [400]".
I checked with Curl, that my DeepL key ist still working and my DeepL Account shows, it is active and I am still in budget for free translations.
Otherwise it was very useful for getting translations quickly. Better translations by using DeepL, a free API key gives you enough headroom for translating 500.000 words per month.

I've been using in the last few years. It's easy to use, easy to modify, feature-rich, and lightweight.

Not translating the complete text and the result is completely mixed.

wrong translation

Best

The only extension I found where I can enable automatic translate upon selecting text (without displaying the button). Thank you very much for your great work!

Forte dégradation de la qualité des traductions depuis quelques jours. Elles ne veulent rien dire par moment. Du coup extension inutile si rien n'est fait.

Good integration, but translation accuracy is terrible compared to Google Translate. I wonder if something changed.

Übersetzung Englisch- Deutsch leider schlecht, teilweise kaum verständlich!

no auto focus in input box when popup open

good

好用
