fixrefox 67 - support for CSS media query prefers-color-scheme not working

[Barry Scott]

I have firefox 67 install on f30 and its not honouring the prefers-color-scheme CCS media query.

I use KDE in dark mode.

This works for Firefox 67 on macOS.

Is this expected to be working? Should I create bug report for this?

I am using firefox 67 in dark mode on F28 in LXDE and it is working as
expected.  So, I suspect that the problem resides in KDE rather than
firefox.  However, open it against firefox; if it isn't firefox the
maintainer will move it to KDE.

Maybe someone on KDE in F30 can confirm that it doesn't work for them
also, or that it does and it is something in your configuration
causing the problem.

Note that KDE-specific questions are better directed to the Fedora KDE
