最好用的翻译扩展。全免费，划词翻译可以选择deepl，网页翻译可以选择google，鼠标悬停显示原文。即使开发者不收费我也想花钱支持一下他，真不容易。
The best translation extension to use. All free, scratch translation can choose deepl, webpage translation can choose google, mouse hover to show the original text. Even if the developer doesn't charge me, I still want to spend money to support him, it's not easy.
