In-depth safety analysis
Vertical Tabs requests sidePanel, tabs, tabGroups, storage, favicon, and contextMenus permissions. These are typical for a tab management tool: it can read and display your open tabs in a side panel, organize them into groups, and add a right‑click menu. The scope is normal and expected for this category of extension.
Any browser extension with the "tabs" permission can see the URLs and titles of all open tabs, including sensitive pages like banking or email. Users should be aware of this access and review the developer’s background, especially when publisher identity information is limited. For any tab organizer, it is good practice to only grant such access to extensions you trust and to keep them updated.
This extension’s strongest dimension, Maintenance & Ownership, earned a perfect score, indicating active upkeep and stable source. Its weakest area is Publisher & Identity, which may mean there is less verifiable public information about the developer. While that does not indicate a problem, it can be a useful signal for users who prefer more transparency before installing.

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.
