Firefox 149 Debuts Linux XDG File Picker, JPEG-XL Decoder, and Free VPN
Firefox 149 brings several improvements, including faster PDF handling and a move to a memory-safe JPEG-XL decoder (jxl-rs), though this JPEG-XL change is currently kept to nightly builds and not in the stable release. On Linux, Firefox now defaults to the XDG portal file picker (with GTK3 fallback); users can download images from PDFs via the context menu, and HTTP/3 uploads are more robust. The release also features updated error pages, new developer APIs, and a built-in free VPN offering up to 50 GB per month. Binaries are available from Mozilla’s FTP site.
