- Dark - Go into complete dark mode. All colors, small images and icons will be converted to give you the smoothest dark experience possible.
- Filtered - The websites' colors will not be changed, but you can still adjust brightness, contrast, warmth and more.
- Normal - Get back to the normal browsing experience.








What is Firefox Dark Mode
More and more web surfers are starting to use dark mode (negative polarity) on their screens. With this mode, light characters are displayed on a dark background which provides better character contrast and is making the display less prone to flicker, thus leading to positive impact from two perspectives. From health aspect, symptoms like digital eye-strain, headaches and blurred vision from continuously starring at the screen are reduced to minimum. From visual perspective, the dark mode interface is way more stylish and cooler. In the end, your user preference should be the determining factor when setting display polarity.
