Firefox Headless ---Screenshot not working for local HTML files
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
