Change inactive tab text/icon color?

[digdut]

Hi There,

I'm using Firefox Lepton with DWMBlurGlass, and I find that the inactive tabs and minimize/maximize/exit icons are hard to read with the color scheme, especially when the window is inactive. I'd like to change it to match the white text and icons when in dark mode without having to set windows to dark mode.

I don't know much about CSS, and I can't seem to wrap my head around it, so any help would be very much appreciated.
