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.

paid for the pro ver. and downloaded it to my new imacs. not working at the moment.

Did nothing when I selected japanese text.. absolutely nothing after selecting translate selected text.

На выделенный текст открывает вкладку с переводом. Когда ввожу текст сайты моргают

Хрень какая то не рабочая.

"DeepL needs to access and process the texts you are reading and writing". That is ridicoulous. They want to have access to our account, to track and read what sites we are visiting. Nope and bye.

Nach einem Update und integration in FF Meldet DeepL dass die app beschädigt ist und entfernt werden soll. Eine Entfernung ist nicht Möglich.

Requires full access to your data on all websites, including your login names and passwords, to even work. Worthless as is.

Il ne se passe absolument rien que je fais traduire cette selection

Very bad

"needs to access and process the texts you are reading and writing." This is completely unnecessary and should be optional. Several 1/2 star reviews point this out, yet DeepL doesn't care (?).

DeepL needs to access and process the texts you are reading and writing. Really?

Убили расширение. Есть аналоги Иишных расширений для быстрого перевода ?

To provide you with translations and writing assistance, DeepL needs to access and process the texts you are reading and writing.

Um Ihnen Übersetzungs- und Schreibhilfen anbieten zu können, muss DeepL auf die Texte, die Sie lesen und schreiben, zugreifen und diese verarbeiten.

Ich bin wohl zu dumm die Erweiterung zu bedienen. Bei mir macht sie überhaupt nichts.
