UPDATE: As of 2-May-2017 this dark mode is now official in YouTube and you no longer need this extension! See here https://www.youtube.com/new
Enables YouTube's secret dark mode by setting a known cookie to enable server-side styling and a new page layout from YouTube itself. Unlike some other extensions, it does not change the HTML or style sheets after they are downloaded.
The first time it is enabled and you load youtube.com, it will display a desktop notification indicating the you'll need to reload the page, and enable Dark Mode in the settings menu to see it in dark mode.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
