Facebook has been testing a dark mode for some time, whether on its website (PC, Mac, Linux) or iPhone and Android application. To take advantage of this, the feature normally needs to be pushed to your account – if you're part of the beta program. However, a trick in Google Chrome allows you to force its appearance.

Dark mode or Dark Mode is spreading little by little everywhere: smartphone applications, operating system, websites… this mode has several advantages. First, it ends the dominance of black-on-white text-like designs that have been virtually integral to the internet since its inception. But it's not just a revolution in style: these designs seek to introduce softer contrasts for the eyes, while causing less emission of blue light harmful to the sleep cycle in the evening or in the dark.



The dark mode also saves a significant amount of energy on some smartphones. This is essentially true for smartphones with an OLED screen, because on them a dark pixel consumes much less energy than an illuminated pixel. Dark mode has been desired for years on Facebook, and is still considered a feature in the process of being tested. However, it is possible to cause its forced appearance recently, thanks to Google Chrome.

How to Enable Facebook Dark Mode on PC and Mac

For it :

  1. Make sure you have the latest version of Google Chrome (79)
  2. Open Google Chrome
  3. In the address bar, type chrome://flags
  4. In the search box type Dark Mode
  5. Enable the Force Dark Mode for Web Contents property by choosing Enabled

You can return to standard mode at any time by returning to chrome://flags and changing this property to Disabled. This dark mode is automatically generated by Chrome. So it's not perfect – expect some errors like negative images.



How to Enable Dark Mode on Android and iPhone

You can again make it appear via the Google Chrome application. Alas it does not yet work directly in the official Facebook application:
