NflxMultiSubs 2021 is a Chrome extension developed by gmertes that allows users to unleash bilingual subtitles on Netflix. This updated version is a fixed and improved re-release of the original NflxMultiSubs, specifically designed to work with the 2021 Netflix redesign.

With NflxMultiSubs 2021, users can enable secondary subtitles in various languages, including image-based subtitles like Japanese, Chinese, and Russian. The extension offers three subtitle activation modes: disabled, automatic matching of subtitle language to audio language, or remembering the last selected language.

One of the standout features of NflxMultiSubs 2021 is its seamless integration with the native Netflix player UI, allowing users to switch languages in place without any hassle. Additionally, the extension provides a hotkey to adjust playback speed, making it convenient for users to customize their viewing experience.

It's worth noting that NflxMultiSubs 2021 is free and open source, adding to its appeal. If users encounter any bugs, they can report them by creating an issue on Github or contacting the developer via email.
