I appreciate the range of languages and the correct English grammar when this app translates into English. It has a huge # of languages available for translation. My major gripe about this program is that it translates things it should not. For example it translates names, so when I'm watching Ryan Cusick on YT, his channel becomes Ryan "Chicken". Other examples are translation of my Pinterest board Vistas is changed to "Views" and a printmaking technique called Chine Colle becomes "China Glue" although the correct English usage is the French name.

Why does my key not work? I don't understand

Nice, but you can only translate into English...

Option for Auto-Detecting the Language would be nice.

Will be good to be able to translate PDFs which are opened in browser.

Pour installer le plugin DeepL gratuit, il faut entrer sa carte bancaire... non merci :/
A savoir : on ne peut pas traduire la page de addons.mozilla.org, j'ai cru que le plugin ne fonctionnait pas du coup...

It could have been better. The translation is good and convenient, but there is a very big stumbling block - the server is blocked very often, giving the error "service usage limit reached", and starts only after a few days. reinstalling doesn't help

Can't see or change the language that it's translating from. and can't play audio from popup. but otherwise great add-on.

翻译页面这个功能在国内用不了
This extension doesn't work in China

1. It's not works on some pages for example "https://addons.mozilla.org/ru/firefox/addon/simple-translate/". It can't translate any word.
2. It has conflicts with Internet Download Manager! Sometimes it hangs next to the IDM download small icon.

ページ翻訳時、新しいページで表示されるので、ちょっと遅いです。
当該ページで翻訳して欲しい。
なので現在は「ウェブページを翻訳」を使用してます。

Eklentiyi yıllardır kullanıyorum, en hızlı çalışan eklenti fakat çoğunlukla belli bir sayıda çeviriden sonra hata veriyor.

Is excelent but, why is a limit time? I need to pay for the extension?
