Hello! I have reproduced the issue with macOS 26 aarch, 14 aarch and 10.15 Intel with Firefox 154.0a1 (2026-06-16). Printing Wikipedia to PDF using the system dialog will not save a PDF file. The file is correctly saved when printing via PDF using the system dialog with `print.prefer_system_dialog: true or false` with the build from comment 6 on macOS 26 aarch, 14 aarch, and 10.15 Intel. If more information is needed, please let me know. Thanks!
