How can I use the "prefers-color-scheme: dark" CSS media query on FF Developers Edition, Ubuntu 18.04?

I'm trying to test latest CSS properties that I think FF 67 supports. Specifically:

prefers-color-scheme: dark

Is this something I can set in FF? Or is this an OS level integration?

Thanks.

It's OS based and probably you can't set the dark mode in Ubuntu. It works in Win10 and perhaps in Mac.

But according to bug 1529323, devs are considering setting 'prefers-color-scheme: dark' when the dark theme is chosen in Firefox.
