Translations

Based on Firefox, Zen also inherit its translation features, allowing you navigate websites in various language easily. The translation process are done locally on your device, instead of relying in cloud services. You can translate a whole page, translate a specific text selection, or translated a link text!

Translating the full page

When you visit a webpage in a supported language, the translation panel will popped up automatically. You can also do it manually by opening Main Menu button and selecting Translate page option.

Zen detects the page languages manually and will suggest to translate it to your preferred languages. You can use the "Translate from" dropdown menu to change page language to detect, and use the "Translate to" dropdown menu to change your translation output language. Select "Translate" to translate the entire page.

The Translate button in URL bar will be updated along with the translation process, and after the translation process gets completed, your preferred language will be shown beside the icon.

To revert the page to the original language, click the Translate button in the URL bar and select "Show original".

Translating text selection

You can also translate a specific word or sentence, which will be handy when reading pages or learning in a foreign language. Select the text you want to translate, right click, and select "Translate Selection to..." option.

The selected texts will be translated and displayed in a pop-up. Select "Copy" to save the whole translation to your clipboard, "Translate full page" to translate the entire webpage, or "Done" to close the pop-up.

You can also select a text manually to copy only a specific part of your translation, or change the input and output translation language using the "From" and "To" dropdown menu.

You can also right click a hyperlink without selecting any text, and select "Translate Link Text to..." to translate the link text.

What if I encounter a page with mixed languages or contents in multiple languages?

The translation feature primarily focuses on the main language of the webpage, so it might not handle pages with mixed languages or content in multiple languages optimally. You can translate specific part of the webpage that uses one language and do this multiple times for different parts to understand the webpage better.

You can tailor your translation experience from two places: the translation panel pop-up and the "Language & Appearance" section in Settings.
