YouTube 繁體自動翻譯修正 is a Firefox extension designed to improve the accuracy of traditional Chinese subtitles on YouTube. This subscription-based tool modifies subtitle settings when the YouTube language is set to traditional Chinese, adding a 'Fix' label to enhance user experience. Even if the language is set to something else, the functionality for correcting subtitles remains active, ensuring that viewers can enjoy better translations regardless of their language settings.

This program falls under the Education & Reference category, specifically focusing on Languages & Translation. By providing automatic corrections to subtitles, it aims to support users in understanding content more effectively. The extension is also available for Chrome, allowing broader access for users across different browsers. The GitHub repository offers transparency and potential for further development, making it a valuable tool for those who frequently engage with Chinese-speaking content on YouTube.
