YouTube Remote Control
This allows you to remote control a YouTube window running on a laptop or desktop from the YouTube app running on your phone or other mobile device.
What is YouTube Remote Control?
YouTube Remote Control is a Firefox add-on that allows you to remote control a YouTube window running on a laptop or desktop from the YouTube app on your phone or other mobile device. Simply link your devices and whatever you play in the YouTube app on your phone will play in the YouTube window on your laptop or desktop, providing a convenient way to control YouTube playback across devices.
Out of the box youtube.com/tv won't load in a regular browser, only on a TV. But this extension changes that, which lets you remote control a YouTube browser window from your phone or other mobile device.
Open youtube.com/tv from a laptop or desktop. This is the window you'll be remote controlling.
click the Settings icon at the bottom left of that window, then "link with TV code" and it'll show you a code.
open the YouTube app on your phone and go to Settings > Watch on TV > Enter TV Code and enter that code and press the "link" button. You should now see a cast icon at the top of the app, click it.
Or in theory, if you're on the same wifi network, you can simply open the YouTube app on your phone and have the cast icon appear even without manually linking, but this doesn't work as reliably.
After linking, whatever you play in the YouTube app on your phone will play in the YouTube window on your laptop or desktop. Whoo hoo!
To stop casting, click the Cast icon again and choose "disconnect".
YouTube Remote Control is risky to use as it requires a number of sensitive permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install YouTube Remote Control if you trust the publisher.
YouTube Remote Control has earned a fairly good reputation and likely can be trusted.
