In-depth safety analysis
The extension requests permissions for storage, tabs, tabGroups, sidePanel, favicon, commands, and bookmarks. This set is expected for a vertical tab manager: it can read tab URLs and titles, create and modify tab groups, manage bookmarks, and use the side panel interface. It does not request broad host permissions, so it cannot directly access page content, but the tabs permission lets it observe browsing activity.
Tab management tools inherently handle sensitive browsing data. Users should verify that the publisher’s privacy policy clearly explains how tab information is used and whether it is transmitted externally. Even with developer-declared commitments not to sell data, a cautious approach is reasonable, especially since the extension stores settings and may sync data via the storage permission. Browser extensions with access to bookmarks and tabs can be appealing targets for impersonation, so installing from the official store and checking for consistent update history helps reduce risk.
The fact sheet shows a perfect Maintenance & Ownership score, indicating active maintenance and clear ownership. The weakest dimension is Publisher & Identity, which scored 60%, suggesting less verifiable information about the organization behind the extension. This makes it wise to examine the publisher’s website and any public presence before trusting it with tab data.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
