YouTube videos missing quality options on this browser
YouTube videos are available in many formats and resolutions. However, some browsers do not support newer video formats. This means these browsers may only have one or two video formats to choose from. We recommend upgrading your browser or operating system for the best viewing experience.
Below are some browser and operating system combinations that support YouTube's high-quality video formats:
- Google Chrome (all operating systems)
- Internet Explorer or Edge on Windows 8.1 or newer
- Safari on Mac OS X 10.10 or newer
- Firefox on Windows 7 or newer and on Mac OS X 10.10 or newer
