I enjoy watching YouTube videos at night as they take away a lot of stress and fill the moments with happiness. As a user, I badly wanted to see Dark Mode in this app to prevent my eyes from straining and have better sleep. That's why I'm so glad to be able to finally enable dark mode in Chrome and Firefox both on Mac and Windows PC.

When you activate Dark mode, it turns the light surfaces of the page dark, thereby providing a fabulous viewing experience at night. This brand new feature is available for Chrome and Mozilla. Let me show you how it works perfectly!
