Problem: A navigation could intermittently hang forever with no load event ever firing. In test-web, that surfaced as a 120-second “pre-navigation timeout, WebContent process may be unresponsive”: The about:blank load used for clearing the document between tests would never complete — leaving WebContent idle while the harness waited. Cause: begin_navigation claims the navigable’s ongoing navigation id and then awaits an asynchronous unload check. While it waits, a session- history traversal can re-stamp the navigable’s ongoing navigation to “traversal”. When the unload check resumes, the navigation finds that its ongoing navigation ID no longer matches — and silently aborts. But nothing ever re-runs it — so the navigation is lost. The deferral guard at the top of begin_navigation, which defers a navigation while a traversal is already ongoing, runs before this window — so a traversal that begins during the unload check slips past it. Fix: When the post-unload-check guard finds the navigable is now running a traversal, re-defer the navigation into the pending navigations list instead of dropping it — mirroring the existing deferral guard. Clearing the ongoing traversal drains the pending navigations — so the navigation runs to completion as a fresh attempt once the traversal finishes.

Ladybird
Ladybird is a truly independent web browser, using a novel engine based on web standards.
Important
Ladybird is in a pre-alpha state, and only suitable for use by developers
Features
We aim to build a complete, usable browser for the modern web.
Ladybird uses a multi-process architecture with a main UI process, several WebContent renderer processes, an ImageDecoder process, and a RequestServer process.
Image decoding and network connections are done out of process to be more robust against malicious content. Each tab has its own renderer process, which is sandboxed from the rest of the system.
At the moment, many core library support components are inherited from SerenityOS:
- LibWeb: Web rendering engine
- LibJS: JavaScript engine
- LibWasm: WebAssembly implementation
- LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security
- LibHTTP: HTTP/1.1 client
- LibGfx: 2D Graphics Library, Image Decoding and Rendering
- LibUnicode: Unicode and locale support
- LibMedia: Audio and video playback
- LibCore: Event loop, OS abstraction layer
- LibIPC: Inter-process communication
How do I build and run this?
See build instructions for information on how to build Ladybird.
Ladybird runs on Linux, macOS, Windows (with WSL2), and many other *Nixes.
How do I read the documentation?
Code-related documentation can be found in the documentation folder.
