Your question bring me to the answer! I was troubling with the same and recently discovered how to do it.

OS

• Ubuntu 18.04.4 LTS (64-bits)

If you have another OS on which it also worked, please add a comment below and I will add it (or add it yourself editing this answer).

Browser details

• Mozilla Firefox for Ubuntu
• Version 78.0.1 (64-bit)

Steps to reproduce

1. Press F12 (open Developer Tools)
2. Press F1 (or go to the "..." button at the top right corner and then press "Settings")
3. In Themes select Dark
4. Done

It's quite an odd choice from Firefox to derive JSON document's color scheme from dev tools theme. Home screen for example uses the browser theme, and I think every other page should too. – Newborn
