In-depth safety analysis
This extension can manage your tabs and tab groups, store settings locally, display its own side panel, access tab favicons, and add items to the right-click context menu. These permissions are typical for a tab management tool, as it needs to organize and display your open tabs in a vertical list. The side panel permission lets it show its interface in the browser's side panel area, which is expected for this category.
For any tab manager, a careful user should know that the "tabs" permission allows the extension to see the URLs and titles of all open tabs. This is necessary for it to list and organize them, but it means the extension has broad visibility into your browsing activity. The developer states they do not sell your data or use it for unrelated purposes, which is a positive signal, but these are self-declared practices.
The strongest dimension in the fact sheet is Maintenance & Ownership, indicating the extension is actively maintained and its ownership is clear. The weakest is Publisher & Identity, which suggests there is less publicly available information to verify the developer's background or reputation beyond the store listing itself.

Who's Behind Vertical Tabs?
- Publisher samihaddad.dev
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.
