Is Close Duplicate Tabs Safe? — Extension Safety Profile

This extension requests the tabs, tabGroups, and windows permissions, which allow it to read the URLs and titles of all open tabs, move tabs between windows, and manage tab groups. The storage permission lets it save user preferences, while alarms enables scheduled duplicate checks. The contextMenus and commands permissions add right-click options and keyboard shortcuts. For a tab cleanup tool, this permission set is typical and necessary to identify and close duplicate tabs.

Because this is a general browser utility, the main safety consideration is whether the developer can be trusted with broad access to your browsing session. The publisher’s identity is the weakest dimension in the fact sheet, meaning there is limited public information about IdleDev. A careful user should consider that small or lesser-known publishers cannot always be easily held accountable. The developer has declared they do not sell data, use it for unrelated purposes, or for creditworthiness, but these are self-reported claims.

The extension’s strongest dimension is Maintenance & Ownership, with a perfect score indicating recent updates and active development. This is a positive sign that the extension is kept compatible and its code is tended to. Combined with a Manifest V3 structure and a solid community reputation score, the technical foundation appears sound, but the anonymous publisher remains a point to weigh.
