Extension Details
Context-Aware Verdict
The extension has a substantial user base of 2 million users and a solid 4.5-star rating from nearly 10,000 reviews, which suggests legitimate functionality and user satisfaction. The developer maintains a dedicated website (sound-ultimate.com) which adds some credibility. However, the high user count alone doesn't guarantee safety, as malicious extensions can accumulate users before being detected.
The extension's permissions are excessive for a simple volume booster. The combination of tabs permission, tabCapture, and broad host permissions (<all_urls>) creates significant privacy and security risks. A legitimate volume booster should only need audio-related permissions, not the ability to access all websites, capture tab content, or manipulate browser tabs. The content script injection across all URLs is particularly concerning as it could be used to steal credentials, modify web pages, or track browsing behavior across all sites you visit.
Consider running this extension in a separate Chrome profile to isolate potential risks from your main browsing activities. Look for alternative volume booster extensions with more limited permissions that only request audio-related access. If you must use this extension, regularly monitor your browser for unusual behavior and avoid using it while accessing sensitive websites like banking or email services. Review the extension's actual functionality to ensure it matches its stated purpose.
