Extension Details

Rating: 4.8 ★ (21 ratings)

Users: 30,000

Context-Aware Verdict

CRITICAL

Overall Risk

Trust Factors:

The extension has a decent user base of 30,000 users and a high rating of 4.8 stars, which suggests users find it functional. However, the limited number of reviews (21) relative to the user count is concerning. The lack of visible author and developer information significantly undermines trust, as legitimate ad blockers typically have transparent development teams or established companies behind them.

Concerns:

The extension requests an excessive number of permissions that far exceed what's necessary for basic ad blocking functionality. The combination of tabs, webNavigation, and broad host permissions creates a surveillance capability that could track all browsing activity across every website. The scripting permission with content script injection on all URLs means this extension can read and modify any webpage content, potentially capturing sensitive information like passwords, financial data, or personal communications. The unlimitedStorage permission combined with these broad access rights suggests potential data harvesting capabilities.

Recommendations:

Do not install this extension due to its critical risk level. If ad blocking is needed, use well-established alternatives like uBlock Origin or AdBlock Plus, which have transparent development teams and more limited permission requests. If you've already installed this extension, remove it immediately and consider running a security scan. The excessive permissions combined with anonymous development make this extension unsuitable for safe browsing, regardless of its apparent functionality.
