YouTube Auto LD
Set your default YouTube video quality to a low definition to save resources. Most videos don't need HD anyway
What is YouTube Auto LD?
YouTube Auto LD is a Firefox add-on that allows you to set your default YouTube video quality to a low definition, such as 360p, saving resources without compromising your viewing experience.
YouTube assumes that everyone wants videos at the best quality available for their connection and screen resolution, but many (if not most) videos are actually just fine at a lower resolution, like 360p: this extension thus makes 360p the default resolution, but it can be customized to other low resolution values.
YouTube Auto LD may not be safe to use and it requires some risky permissions. Exercise caution when installing this add-on. Review carefully before installing.
YouTube Auto LD is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
