80s retro futurism dark av shafto

if you want to remove white flash before page load, you need to go to
about:config and set browser.display.background_color to #1B1B1B (might break some sites that use browser's default background color)

This is an update to a theme by vxnicios I've made because I didn't like white page on new tab. Please let me know if there's something that can be improved, I'd like to hear new ideas for this theme.
