Restricted Mode is an optional setting on YouTube that can be turned on or off. It is designed to help screen out potentially mature content that viewers or others using their devices may prefer not to view. Restricted Mode intentionally limits the YouTube experience by blocking potentially harmful or inappropriate content. It is turned off for viewers by default. Restricted Mode can be enabled on the YouTube website and app, and it works at a browser level, so if you choose to use it, you will need to turn it on in each browser installed on your device. Viewers who turn on Restricted Mode cant see comments on videos. Restricted Mode may also be turned on for computers in libraries, schools, and other public institutions by the institutions system administrator. To turn Restricted Mode on or off, viewers can follow the steps provided by YouTube.
