• Video Titles: Keep titles in their original language (Video titles, Shorts, Notifications...)
• Audio Tracks: Always use the original audio track (or choose a specific one)
• Descriptions: Prevent automatic translation of videos descriptions
• Thumbnails: Restore original thumbnails
• Subtitles: Set your preferred subtitle language, if unavailable, subtitles are disabled (auto generated ones are ignored)

You can enable YouTube Data API v3 (requires your own API key) for the most reliable and fastest way to fetch original data. Learn more.

If you want to use the DeArrow extension alongside this one PLEASE CHECK THIS to avoid any conflicts.
