Summary
Mozilla has released Firefox 149, bringing several significant improvements to its cross-platform web browser. The update introduces jxl-rs, a Rust-based JPEG-XL image decoder that replaces the previous C++ implementation, aligning Mozilla's approach with Google Chrome's memory-safe strategy. On Linux systems, Firefox now defaults to the XDG portal file picker where available, while maintaining fallback support for GTK3.
Beyond the decoder upgrade, Firefox 149 delivers performance enhancements including faster PDF file handling, improved HTTP/3 upload performance, and new context menu functionality for downloading images directly from PDFs. The release also introduces a free built-in VPN offering 50GB of monthly data transfers, alongside redesigned error pages and numerous new developer APIs to improve the development experience.
