In-depth safety analysis
The extension requests bookmarks, tabs, scripting, activeTab, storage, and sidePanel permissions. This allows it to read and organize all open tabs, store settings, and inject scripts into the active page when you interact with the extension. For a tab tree manager, access to tab information is essential, and using the side panel is expected. The scripting permission combined with activeTab limits script injection to pages you explicitly invoke the extension on, rather than all websites.
Tab management extensions can see the URLs and titles of every open tab, so they have broad visibility into your browsing. Users should be comfortable with the developer having this access. The fact sheet shows a safety score of 77 out of 100, with the weakest dimension being Publisher & Identity (60%), suggesting limited public information about the developer. The strongest dimension is Maintenance & Ownership (100%), indicating the extension is actively maintained, which is good for security. The community rating of 3.7 out of 5 from 93 users provides moderate social proof.

Who's Behind Tree Style Tab?
- Publisher xingtanzjr
Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
