DeepL Tool от Juuroku

Enter, copy or select text, and open a new tab with DeepL to translate.

You can open popup and either enter the text or copy from your clipboard, or you can select the text and right-click the mouse to access the add-on from context menu.
Clicking the 'Translate' button will active a new tab with DeepL.

Starting from v1.2, you can now open a new tab with DeepL directly from the context menu, the target language can be configured in options page.
The target language can be configured in the options page, with the default set to your browser's UI language.
In v1.2, you need to submit options at least once to use this function, otherwise an error may occur. The issue has been fixed in v1.2.1.

Starting from v1.1, you can also add a DeepL auth key in the options page to translate in-page without opening a new tab.
Select the text ,right click, and choose 'DeepL API Inpage Translate' to display the translation result in the bottom right corner of the webpage.
