Is Super Video Speed Controller Safe? — Extension Safety Profile

This extension can read and modify data on every website you visit because it requests host access. Combined with the scripting permission, it can inject JavaScript into any page to control video playback speed. The declarativeNetRequest permission allows it to modify network requests, which could be used to redirect or block content. While these capabilities are technically necessary for a video speed controller to function across all sites, the scope is unusually broad and gives the extension significant power over your browsing.

Video speed controllers are a popular but generally low-risk category. However, users should be aware that any extension with access can technically see sensitive information like login forms or financial pages if it chooses to. The publisher's identity score is relatively low, which means there is less publicly verifiable information about the developer. A careful user might consider whether they trust an extension from a less-established publisher with such wide-reaching access.

The extension's strongest dimension is Data & Privacy, with a perfect score based on the developer's declarations that data is not sold or misused. Its weakest area is Permissions & Access, reflecting the powerful host permissions granted. The community reputation is strong, suggesting most users have a positive experience, but the permission model remains something to weigh carefully.
