Firefox for iOS includes a Night Mode feature to invert webpage colors to a dark theme, reducing eye strain in low-light conditions and potentially saving battery life. Follow these steps to enable or disable it:

Enable Night Mode

  1. At the bottom of the screen, tap the menu button Menu hamburguer button (the menu will be at the top right if you're using an iPad):
  2. Tap Turn on Night Mode to invert the webpage to a dark theme.

To revert the display back to its original theme, simply follow the steps above once more.
