Firefox 157 will include JPEG XL by default on all platforms
Summary
Firefox 157 will enable JPEG XL decoding by default on all platforms. The discussion notes that JPEG XL support has been in Firefox behind image.jxl.enabled and in Nightly, with a Rust-based jxl-rs decoder, and references standardization via ISO/IEC 18181. Benchmarks and cross-browser context (Safari 17.0, Chrome) are discussed, along with ongoing testing, animation support, HDR tone mapping, and plans to ship by default after further performance work.
