Auto Theme

Some web apps allow you to set an app-specific dark/light theme preference, but have no option to match your system default. These extensions toggle apps' existing dark/light themes in sync with your system preference.

**This extension is now obsolete due to Facebook adding the “Automatic” option under Display & accessibility settings.**

You can set Facebook to have a dark or light theme, but not to have it match your operating system dark/light theme. This extension matches your Facebook theme to your system theme.

It only works on parts of Facebook that support dark theme, so it works on the New Facebook.com and parts of Facebook Workplace, but not Instagram or Messenger.com.

**This extension is now obsolete due to Feedly adding the “System Preference” option under Appearance settings.**

You can set Feedly to have a dark or light theme, but not to have it match your operating system dark/light theme. This extension matches your Feedly theme to your system theme. It does not modify the theme setting in your Feedly settings, so if you uninstall the extension, it will revert to your previous setting, and if you use it on multiple devices, it will match each device's system theme.

**This extension is now obsolete due to Discord adding the “Sync with computer” option under Appearance settings.**

You can set Discord to have a dark or light theme, but not to have it match your operating system dark/light theme. This extension matches your Discord theme to your system theme. It does not modify the theme setting in your Discord profile, so if you use it on multiple devices, it will match each device's system theme.
