In-depth safety analysis
This extension requests permissions to read and modify open tabs, manage tab groups, access browsing history, and use storage for settings. The management permission stands out because it allows control over other installed extensions and themes, which is broader than what most tab managers need. This set of permissions is partially expected: tab and tab group access is essential, but the ability to interact with other extensions may be more than a user anticipates for a tool focused on organizing tabs.
For any general browser extension that can see active tabs and history, a careful user should be aware that the developer could, in principle, collect a detailed log of visited pages. Since tab managers often handle sensitive URLs, it is wise to stick with well-known publishers. Here, the publisher is an individual (xcv58) with a limited public identity track record, which might give some users pause. No evidence of misuse exists, but users should consider whether they trust a less-established developer with broad visibility into their browsing activity.
The fact sheet shows a safest dimension of Maintenance & Ownership, indicating the extension is actively updated and its ownership is clear, reducing risks from abandonment or unclear control. The weakest dimension is Publisher & Identity, reflecting the lower confidence in the publisher's verifiable background. This balance suggests a functionally sound tool from a less-verified source, so a user’s comfort will depend on their tolerance for publisher anonymity.
