Context-Aware Verdict

MEDIUM

Overall Risk

Trust Factors: The extension has a reasonable user base of 40,000 users with a solid 4.4-star rating from 65 reviews, indicating generally positive user experiences. The functionality described (undoing closed tabs) is straightforward and commonly needed. However, the lack of visible developer information and missing last updated date raises some transparency concerns.

Concerns: The tabs permission is the primary concern here, as it grants broad access to browser tab information and manipulation capabilities that extend beyond what's strictly necessary for reopening closed tabs. While the storage and sessions permissions are appropriate for maintaining tab history, the tabs permission could potentially be misused to monitor browsing activity, access sensitive tab data, or manipulate tabs in unintended ways. The extension's small size and basic functionality don't clearly justify such extensive tab access rights.

Recommendations: Consider running this extension in a separate Chrome profile if you handle sensitive information in your browser. Before installing, verify that simpler alternatives exist that might require fewer permissions. Monitor the extension's behavior after installation to ensure it only performs its stated function. Given the medium risk level, you could also use Chrome's built-in Ctrl+Shift+T shortcut as an alternative that requires no additional permissions. If you proceed with installation, regularly review your installed extensions and remove any that seem unnecessary.
