ASS Subtitle Player

Enhance your streaming experience with ASS Subtitle Player! This lightweight and powerful extension allows you to overlay your own local subtitle files onto any web-based video player.

Whether you are watching anime on HiAnime or enjoying content on other streaming platforms, this extension ensures you can use your preferred subtitles with professional-grade rendering.

✨ Key Features:

• Format Support: Full compatibility with .ass, .ssa, and .srt files.
• HiAnime Optimized: Specially designed to work within iframes, ensuring the subtitle picker triggers correctly even on complex video hosting sites.
• Modern Popup UI: A clean, distraction-free interface. No more messy buttons cluttering the video page—everything is managed from the extension panel.
• Aspect Ratio Toggle: Easily switch between 16:9 and 4:3 modes to prevent subtitles from overlapping with black bars.
• Clear Rendering: High-quality subtitle rendering with outlines and shadows for maximum readability.
• Mobile Friendly: Fully compatible with Firefox for Android.
• Privacy First: No data collection. Your subtitle files are processed entirely locally in your browser.

1. Navigate to any website with a video player (e.g., HiAnime).
2. Click the ASS Subtitle Player icon in your browser toolbar.
3. Click the "📁 Select Subtitle" button.
4. Choose your subtitle file from your device.

Many extensions struggle with modern video sites that use nested iframes. ASS Subtitle Player uses a smart broadcasting system to detect the video player wherever it is hidden on the page, providing a seamless "plug-and-play" experience.
