Last scanned: about 8 hours ago

Extension Details

Developer: ADBLOCK, INC.

Rating: 4.5 ★ (290.4K ratings)

Users: 61,000,000

Context-Aware Verdict

MEDIUM

Overall Risk

Trust Factors:

AdBlock is a well-established ad blocking extension with 61 million users and a strong 4.5-star rating from nearly 300,000 reviews. The extension is developed by ADBLOCK, INC., a legitimate company in the ad blocking space. The high user base and positive ratings suggest the extension has been thoroughly tested by the community and generally performs as expected.

Concerns:

While the security analysis flags this as "Critical" risk, the permissions are largely necessary for ad blocking functionality. The webRequest and webNavigation permissions are essential for intercepting and blocking ad requests. The broad host permissions (<all_urls>) are required since ads appear across virtually all websites. However, these permissions do create potential privacy risks, as the extension can theoretically monitor all browsing activity and web requests.

The tabs permission allows manipulation of browser tabs, which goes beyond basic ad blocking needs. The unlimitedStorage permission could be concerning if misused, though it may be needed for storing large filter lists.

Recommendations:

Given the extension's reputation and necessity of most permissions for ad blocking, the risk is manageable for most users. However, privacy-conscious users should be aware that this extension can monitor all web activity. Consider reviewing the extension's privacy policy and data handling practices. If maximum privacy is needed, run this extension in a separate Chrome profile or consider open-source alternatives like uBlock Origin.
