Auto HD|LQ for YouTube™

The extension has a reasonable user base of 4,000 users with a solid 4.1-star rating from 40 reviews, indicating generally positive user experiences. The functionality aligns with its stated purpose of managing YouTube video quality settings. The extension uses Manifest V3, which provides better security controls than older versions.

The primary concern is the storage permission, which allows the extension to store data locally on your device. While this is necessary for remembering your video quality preferences across YouTube sessions, it does create a potential privacy consideration as the extension could theoretically store other types of data. The content script injection on YouTube domains is appropriate for the extension's functionality but does mean the extension has access to YouTube page content.

The extension lacks detailed developer information, which reduces transparency about who created and maintains it. Additionally, no last updated date is provided, making it difficult to assess how actively maintained the extension is.

This extension presents minimal security risk for most users. The permissions requested are reasonable and necessary for its stated functionality. Users concerned about data storage can monitor what information the extension saves through Chrome's developer tools. Consider running it in a separate profile only if you're particularly privacy-conscious, though this level of precaution isn't necessary for most users given the low risk assessment.
