I like darkmode too. Besides running Flux, i installed Reddit Slate Nights 2.0 (Dark) for Chrome (i'm on reddit too much, this helps)
I also have "dark fox" for Firefox, similar kinda thing.
Last, i set cmd to transparent with light gray text.
Hardly perfect of course, but these things overall have given my Win10 a pretty dark theme across the board. If anyone else has ideas feel free to chime in!
@Trident: If you don't know how to do thisHigh contrast theme?
In Linux/Firefox I use Global Black Background with Stylish. FB looks good for me.I've done this too. I've also added dark themes for craigslist and hacker news. I'm considering a dark theme for FB but I don't want the website to be broken. (I know how much FB updates its shit)
