I am using Firefox 109.0.1(64-bit) in headless mode from the Command Prompt screen of Windows 10. From the Mozilla Firefox folder if I enter firefox.exe --headless --screenshot C:\Users\me\file1.png https://www.wikipedia.org I successfully store the screenshot as file1.png However, if I enter firefox.exe --headless --screenshot C:\Users\me\file2.png https://www.python.org I don't store any file nor do I get any error message If I enter (not using headless mode) firefox.exe https://www.python.org the Firefox screen is opened and the python.org page is displayed

Any ideas about why wikipedia.org works and python.org doesn't?

I always use a separate test-ss profile for testing in headless mode and if necessary delete all the files in this profile leaving the profile folder empty. This still works for me:

Both sites work for me on Linux with the current 109 release.
