Any native methods to have Firefox display site source code ("View Page Source") in a dark theme (white on black)?

Question

Does Firefox currently have a native way (perhaps an about:config preference) to display the source code viewer ("View Page Source", view-source:) in a dark theme (white on black)?

I performed a search, but didn't see anything relevant.

Before implementing it with userContent.css, I thought it's best to ask.
