  • Latest version

    Version 5.3

    Released 17 May 2026 - 41.58 kB
    Works with firefox 58.0 and later
    • Smart Language Detection: Added a new "Detect Languages" button! It uses offline, built-in, privacy-safe AI to automatically identify and label subtitle tracks that have random, hashed, or missing names.
    • Intelligent Name Preservation: The extension now preserves rich subtitle metadata (like "SDH", "Forced", or Regional tags) when they are available, only overwriting "garbage" filenames (like UUIDs) with the newly detected language.
    • Fixed "Download All": Resolved an issue where bulk downloading would stop after ~5 files due to browser spam protections. Downloads are now safely queued so you can grab dozens of files at once seamlessly.
    • Improved CJK Language Support: Language detection has been fine-tuned to accurately identify dense languages like Chinese, Japanese, and Korean, even on heavily sylized VTT files.
