GoKawiilMozilla to enable JPEG XL image decoding by default in Firefox 157
Mozilla announced it will turn on JPEG XL decoding by default across all Firefox platforms starting with version 157, using its Rust-based jxl-rs decoder. The feature has been available as an opt-in Labs setting since Firefox 152 and behind a hidden preference since earlier releases, and now gains multithreaded decoding to match performance with Safari's implementation.
