i18n 编辑
Functions to internationalize your extension. You can use these APIs to get localized strings from locale files packaged with your extension, find out the browser's current language, and find out the value of its Accept-Language header.
For more details on using i18n for your extension, see:
- Internationalization: a guide to using the WebExtension i18n system.
- Locale-Specific Message reference: extensions supply locale-specific strings in files called
messages.json
. This page describes the format ofmessages.json
.

i18n.LanguageCode
- A language tag such as
"en-US"
or "fr
".
