In-depth safety analysis
The extension requests "tabs," "tabGroups," "favicon," "storage," and "sidePanel." This allows it to read the addresses and titles of all open tabs, organize tab groups, display website icons, store settings, and open a side panel. These permissions are typical for a vertical tab management tool, but the "tabs" permission means it can access your browsing activity while enabled. Only install such extensions from developers you consider trustworthy.
In the general browser extension category, tab managers with broad permissions carry the inherent capability to observe which pages you visit. Cautious users may want to verify that the publisher has a clear identity and consider reviewing the source code if it is available. As with any popular utility, clones or fake versions can appear, so double-check that you are installing the authentic extension from the official Chrome Web Store listing.
The safety evaluation gives a grade A, and the strongest point is Maintenance & Ownership, reflecting recent updates and responsible stewardship. The weakest dimension is Publisher & Identity, indicating that the developer's individual reputation is less verifiable than that of larger organizations. This is a factor to weigh when granting tab-level access to an extension from an independent publisher.
