• You can modify the wallpaper in the userContent.css, and edit the file names for the light and dark modes

body {
	background: url('neptune/image/RainbowLight.png') center/cover no-repeat fixed;

	@media (prefers-color-scheme: dark) {
		background: url('neptune/image/RainbowDark.png') center/cover no-repeat

	}
}

Configuration

• about:config

  • Set toolkit.legacyUserProfileCustomizations.stylesheets to true.
  • Set svg.context-properties.content.enabled to true.
  • Set widget.non-native-theme.use-theme-accent to true.

ENJOY!
