In-depth safety analysis
This extension requests “storage” to save your preferences and access to YouTube domains (*.youtube.com and youtube-nocookie.com). That host permission allows it to read and modify YouTube pages, which is necessary to inject its enhancements—like custom themes, player controls, or layout changes. For a dedicated YouTube enhancer, this permission scope is tightly focused and expected; it cannot read data on other websites.
As with any browser extension that modifies a major site, users should be aware that updates could alter behavior. Always review what an extension is asking for when it updates, and only install from official stores. Be cautious of similarly named clones that may appear in search results.
This extension’s strongest dimension is Community Reputation—it has a large user base (2 million) and a high average rating from many reviews, indicating widespread user satisfaction. Its weakest dimension is Publisher & Identity, which scored lower due to the developer being an independent website rather than a verified corporate entity. However, the extension’s long history, regular updates, and strict privacy declarations help balance that uncertainty.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
