In-depth safety analysis
Tab Manager Plus requests permissions that are expected for its category: the "tabs" permission allows it to view and manage all open tabs, "contextMenus" enables right-click menu options, "storage" saves your settings, and "favicon" retrieves website icons. This scope is normal for a tab manager, though it does grant broad visibility into your browsing activity.
As a general browser extension, it can access the URLs and titles of every open tab. Users should be aware that any extension with the "tabs" permission inherently has this capability. The developer's privacy disclosure states that location data is collected, but also declares it is not sold or used for unrelated purposes. The extension uses Manifest V3, which enforces stricter limits on background data access.
The fact sheet shows a strong Community Reputation score (93%), backed by a high rating and many reviews. The weakest dimension is Maintenance & Ownership (30%), indicating that the publisher's identity and update frequency may be less transparent. A cautious user might weigh this against the positive community feedback when deciding to install.
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.
