I'm unable to generate a screenshot of a local HTML file using Firefox's (v60.9.0) [headless mode][1]

Here's the command I'm using: 

   "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -P AJ --screenshot test.png "file:///C:/html_export.html"

I've tried with and without a profile and with different numbers of slashes after file. There are no errors in the command line - it just doesn't generate an output.

This command works fine when I substitute the file:// with an external website like: 

   "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -P AJ --screenshot test.png google.com

Could it be related to the [redirect bug mentioned here][2]?

Any help is appreciated! Perhaps theres a way to turn on output verbosity for --headless mode?

This could be related to this pref:

  • privacy.file_unique_origin = false

See also this thread for some remarks when I tested headless mode:
