Video Quality Settings for YouTube (HD/4K) 作者： Armin Sebastian

Video Quality Settings for YouTube is a Firefox extension that sets the preferred quality of YouTube videos, and remembers your video quality settings between sessions. Limiting the video frame rate to 30 FPS is also supported.

The continued development of Video Quality Settings for YouTube is made possible thanks to the support of awesome backers. If you'd like to join them, please consider contributing with Patreon, PayPal or Bitcoin.

The video quality is set to 1080p by default when the extension is installed, and the option can be updated from the player settings on YouTube, or from the extension's options. Reload already opened videos for changes to take effect.

The extension is also available for Chrome and Edge.
