Tip

How to Toggle between Light and Dark theme:

There are two settings to change in firefox (pictures below).

• Setting both to auto makes it adapt to your operating system theme.
• Setting Theme(2) to Light or Dark will force it no matter of Operating System colors.
• Best to leave Website Appearance(1) settings set to auto and just Change to preferred Theme(2).
  

1. Website appearance (changes new tab and websites colors)
2. Theme (changes toolbar and browser text colors, also sets text colors to new tab page).

I use firefox integrated Flexible space for spacing:
