I am deeply disappointed with the DeepL browser extension for Mozilla Firefox due to the lack of Arabic language support. While Arabic is available on the DeepL website, it is frustratingly absent from the browser extension. This inconsistency hinders the usability and accessibility for a significant number of users who rely on Arabic translations. As a result, I am giving this extension a one-star rating. I urge DeepL to prioritize adding Arabic support to align the extension's capabilities with those of the website and better serve their diverse user base.

addon doesn't work. I always get an error when I try translate a text.

L'extension ne fonctionne plus du tout sur firefox. le click-droit n'a jamais ouvert la page de traduction, et maintenant que firefox offre son propre outil de traduction, le popup bouton n'apparait plus. a moins de désactiver l’outil de firefox...
CE MODULE A BESOIN D ÊTRE MIS A JOUR !!!!

Le traducteur direct fonctionne parfaitement. L'ad-on de Firefox ne fonctionne pas. Aucun pop-up de traduction n'apparait sur la sélection d'un texte en anglais par exemple.

Übersetzungen, wenn es denn mal Funktioniert nur ungenügend. Da ist Google-Translate deutlich besser, vorallem bei den unterstützten sprachen.
Wird deinstalliert

This is the worst extension I have ever tried in 20 years. It is not working at all and waste of time.

Ne traduit pas une page entière comme peut faire Google Traduction. Utilisez plutôt le traducteur du site directement en copiant le texte

Not working on Reddit

faking too suck

翻訳機能はすばらしいが、とにかく使いにくい。なんでこんなふうに作ったのか意味がわからない。アンインストールしたら FireFox上での Ctrl+C,Cが一切効かなくなった。サポートに連絡しても逆に質問されまくるだけで1mmもサポートしてくれない。翻訳精度が良いだけでほかは全部失格。

I still haven’t figured out how to translate the entire page. There are more convenient, free add-ons.

Limited translation for free usage 🤡🤡🤡. Switched back to "Simple Translate" extension.

Great tool for precise translating. But does not support dark mode - it is big cons! Please fix it.
And please consider option for translating after hover text as TransOver addon is able to. Thank you.

Worst translation addon ever, with the absolute worst support I have EVER witnessed in 60 years life.
I wish them the most disgraceful utter failure.

The extension functionality is A-OK, solid 5/5. It's the implementation that kills it usefulness, and barely scrapes 0/5. I could go into the negative score numbers, but boy, where I would've stopped then...

I had to uninstall the extension because it throws its trash around all over the browser. It injects a humongous CSS stylesheet, 115KB(!) in size, into *every single open tab*, regardless of DeepL translation being ever used. I estimated that I used the selection translation pop-up at about one in every 500 to 1000 pages. This is a truly humongous waste of resources. The stylesheet contains 734 selectors, 2999 property settings and two @media width breakpoints. You'd have a hard time convincing me that this is a bare minimum necessary to display a simple pop-up box…

And then, in any case, a sensibly written extension would have delayed loading its CSS until it is actually needed, i.e. until it actually displays something. And load it into a sandbox, so that it's gone when the pop-up is closed: come think of it, DOM shadow roots were invented for a reason, and scoping resources in time was one of the two major ones. Now, the funny part, albeit not ha-ha funny: the extension does in fact use a shadow root for the pop-up, and… yes, you guessed it, loads another copy of its juggernaut CSS sheet into it. Why it also stuffs all this useless CSS everywhere it only can is beyond me, but loading the CPU with the browser's failing to match the extra 750 selectors every time the layout is recomputed—and "responsive" layouts on dynamically changing pages have to be deeply recomputed often!—isn't something I can use. I have better ways to waste my CPU than this extension.

As soon as the issue is fixed, I'm upgrading my rating to 5/5 not thinking twice. I hope that this is just an oversight, a bad design decision that could be soon reassessed and undone.

doesn't show any translation

Not working as intended.
