CthulhuJs (Anti-Fingerprint)

The extension has a relatively small user base of only 2,000 users, which limits community validation. However, it maintains a decent rating of 4.3 stars from 33 reviews. The lack of visible developer information raises transparency concerns, making it difficult to assess the creator's reputation or track record. The anti-fingerprinting purpose suggests legitimate privacy protection goals, but this functionality inherently requires extensive permissions.

The extension requests extremely broad permissions that go well beyond typical anti-fingerprinting needs. The combination of tabs, webNavigation, and all_urls permissions creates a powerful surveillance capability that could track all browsing activity across every website. The storage permission allows persistent data collection, while scripting and declarativeNetRequest enable content modification. For an anti-fingerprinting tool, these permissions seem excessive and could facilitate data harvesting or malicious behavior. The small user base and missing developer information compound these technical risks.

Given the high risk profile, install this extension only in a separate Chrome profile isolated from sensitive browsing activities. Regularly audit what data the extension might be collecting through Chrome's extension management settings. Consider well-established alternatives like uBlock Origin or Privacy Badger that offer similar fingerprinting protection with better transparency and larger user communities. If you must use this extension, avoid accessing sensitive websites while it's active and monitor your browsing performance for unusual behavior.
