What our analysis found
Tab Session Manager, used by 100,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in July 2026.
The extension 'Tab Session Manager' is a well-known, widely used (100k+ users) session management tool from a trusted publisher (Sienori, 0% malicious other extensions, Google trusted badge). The permissions (storage, unlimitedStorage, tabs, downloads, identity, alarms, offscreen) directly align with its described functionality: tabs/ windows, cloud sync via Google, and exporting sessions. The bundled source files (,) contain standard browser-polyfill code and on-page utilities for; no suspicious network requests, obfuscation beyond normal minification, or unauthorized data collection were observed. The ML model itself gave a low risk score (0.00), and the pre‑computed high‑risk flags from the risk‑engine are based on a superficial permission‑scan that fails to consider the legitimate use case. All signals (publisher reputation, user ratings, category alignment, CWS listing) point to a benign extension.
