Extension Details

Users: 14,000,000

Context-Aware Verdict

MEDIUM

Overall Risk

Trust Factors: This extension has exceptional trust indicators with 14 million users and a strong 4.5-star rating from 2,700+ reviews. The name "uBlock Origin Lite" suggests it's related to the well-known uBlock Origin ad blocker, which is a highly respected privacy tool. The large user base indicates widespread adoption and community trust.

Concerns: The primary concern is the broad host permissions (<all_urls>) which allows access to all websites you visit. While this is functionally necessary for an ad blocker to work across the web, it represents significant access that could theoretically be misused. The activeTab permission adds another layer of site access, though this is standard for extensions that need to interact with web pages. The storage permission allows data retention, which could include browsing patterns.

The version number (2026.125.1931) appears unusual with a future year, which may indicate a versioning scheme issue or potential concern about authenticity.

Recommendations: Verify this is the legitimate uBlock Origin Lite from the official developer before installation. Check the developer information in the Chrome Web Store to confirm authenticity. Given the broad permissions but strong trust indicators, this extension appears relatively safe for most users. However, if you're particularly privacy-conscious, consider running it in a separate Chrome profile or research whether this is indeed the official version of uBlock Origin Lite.
