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.


Auto Theme for Discord

Get for Chrome Get for Firefox Get for Opera
Source Code

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.



Auto Theme for Facebook

Get for Chrome Get for Firefox Get for Opera
Source Code

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.


Auto Theme for Feedly

Get for Chrome Get for Firefox Get for Opera
Source Code

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.
