Extension Details

Developer: theproblocker.com

Rating: 4.9 ★ (225 ratings)

Users: 10,000

Context-Aware Verdict

CRITICAL

Overall Risk

Trust Factors: The extension has a strong 4.9-star rating from 225 reviews, suggesting user satisfaction. However, with only 10,000 users, it has a relatively small user base for verification. The developer domain "theproblocker.com" appears legitimate for an ad blocking service, though limited company information is available.

Concerns: This extension exhibits several red flags beyond typical ad blockers. The combination of webRequest, webNavigation, and tabs permissions creates a powerful surveillance capability that could track all browsing activity. The broad host permissions and content script injection across all websites means it can access sensitive data on banking, email, and other private sites. The webRequest permission allows intercepting and potentially modifying network traffic, which could be exploited for man-in-the-middle attacks. While these permissions might be justified for comprehensive ad blocking, they create significant privacy and security risks if misused.

Recommendations: Given the critical risk level, consider running this extension in a completely separate Chrome profile isolated from sensitive browsing activities. Alternatively, use well-established ad blockers like uBlock Origin or AdBlock Plus that have larger user bases and longer track records. If you choose to keep this extension, regularly monitor your network traffic and avoid using it while accessing sensitive websites like banking or email services. Consider the risk-benefit tradeoff carefully, as many safer ad blocking alternatives exist.
