Ladybird Browser Adds Video Playback on Twitch, CSS Scroll Snap, and JavaScript Debugging
Key points
- Ladybird now supports video playback on Twitch and more YouTube formats.
- CSS scroll snap functionality has been implemented.
- JavaScript debugging is available in Ladybird's DevTools.
- Downloads can now be paused and resumed.
Enhanced Media Playback
In August 2026, Ladybird significantly improved its media capabilities. The browser's Media Source Extensions now support fragmented MP4, AVC (H.264), HEVC (H.265), AV1, and AAC codecs. This allows for adaptive-bitrate video playback on platforms like Twitch and Plex.
YouTube video support was also expanded. While VP9/Opus in WebM already worked, Ladybird can now play older or less popular videos that only offer multiple quality levels in AVC, and higher quality AV1 streams, including 8K content. Several playback bugs were also resolved, addressing crashes with YouTube video-card previews, hanging players using preload="none", and issues with HLS.js-based players.
New Web Layout and Developer Tools
Ladybird introduced CSS scroll snap functionality, including support for `scroll-snap-type`, `scroll-snap-align`, and `scroll-snap-stop`. This feature ensures that scrolling actions, whether by wheel, keyboard, scrollbar, touchpad, or programmatic `scrollTo()`, snap to defined points, and content re-snaps on layout changes. This enables the creation of carousels and full-page scrollers.
For developers, Ladybird's DevTools now include JavaScript debugging. Users can set breakpoints, step through code line by line, and evaluate watch expressions. This core debugging workflow is built on new breakpoint support in the browser's JavaScript engine, with Wasm debugging and DOM mutation breakpoints planned for future releases.
Performance and Core Improvements
The browser also saw a sustained focus on engine performance. Key improvements include a new style engine, layout caching, and moving CSS animations off the main thread. Core architectural changes involved adding caging for cell pointers in JavaScript values and migrating CSS parsing and the painting pipeline to Rust.
User Experience Enhancements
Beyond media and developer tools, Ladybird added user-facing features such as the ability to pause and resume downloads, and session restore functionality. These additions improve the overall user experience and browser stability.
