Extension Metadata

About this extension
HLSify++ is a powerful browser extension that seamlessly improves your HLS (HTTP Live Streaming) video playback experience. It combines the best features from the original HLSify and Native HLS extensions, adding modern enhancements for a smoother viewing experience.

Key Features:
  • Automatic Playback Fix: Ever landed on a page where a video should play but doesn't? HLSify++ detects when a website fails to play an HLS stream and dynamically uses the powerful hls.js library to get it working right in its place.
  • Direct Stream Viewing: No more downloading .m3u8 files when you just want to watch a stream. The extension intercepts these links and opens them in a clean, modern video player powered by Plyr.io.
  • Modern Player UI: The custom player for direct streams is accessible, easy to use, and looks great.
  • Enhanced Subtitle Support: Enjoy better compatibility and rendering for subtitles.

Permissions Explained:
  • Access your data for all sites: This permission is required to detect HLS playback failures on any website. The extension only activates when it finds a video that has failed to play, ensuring minimal impact on your browsing.

Found a Bug or a Site That Doesn't Work?

Your feedback is essential! If you encounter a website where the extension doesn't work as expected, please report the issue on our GitHub repository.

To help us resolve the problem quickly, please include an example link to the page where the video is failing.
