非常に良い
私はwebの翻訳に頼ってたけど軽いのでこちらを導入まず翻訳の精度webサイトで翻訳するより
精度が高いのは謎だがかなり使えるので嬉しい
あとはコンテキストメニューとかコピペするとアイコン出るのは設定で無効化できます。
少し不満な点はコピペしても無反応ときあるのでその時はEnter押さないといけません。
他のアドオンは怪しいのも多いなかこちらはオススメできます。Kasperskyでも安全と判断されました。

The best translate addons. Great experiment

So many minor annoyances with other translators, but this one is just perfect.

Excellent. Fast, immediate.

the best translate, immediate

Make like TransOver for Chrome. Do the translation WITHOUT HIGHLIGHTING

perfect

Кроме того, что не работает на addons.mozilla.org и некоторых других сайтах (скорей всего это проблема гугл переводчика), больше особых претензий нет.
Может переводить выделенный текст, всю страницу и так, как мне нужно. Есть все необходимые настройки.

Need one more feature: input language.

Auto detection doesn't always work well, especially when translating a small passage of text. Japanese is often recognized as Chinese, and you'd never know it, because it display say what language the selected text is detected as. Similarly, Dutch could be detected as German, Spanish as Portuguese, etc.

Input language should perhaps be a priority list of languages you most likely want to translate, and have the translation engine prefer those over whatever is autodetected, if possible.

That's excellent

Good

Very good - simple and fast! Maybe missing option "translate by key"

Bence şuanda en iyisi bu. Çok teşekkür ederim.
Best. Thank you...

Simple, intuitive, quickly accessible and easy way to translate while reading a webpage.

it's great

As described, Simple to use, simple everything

رائع

"Simple Translate" is its name and that's right, it is simple, fast, accurate and very easy to use. I am pleased of using it everyday.
