Is SideTab Pro - Vertical Tabs, Bookmarks and Reading List Safe? — Extension Safety Profile

This extension requests the tabs and tabGroups permissions, which allow it to read the URLs and titles of all open tabs and organize them into groups. Combined with sidePanel for its main interface and favicon to display tab icons, that set is standard for a vertical-tabs manager that needs to show and rearrange your browsing session. The storage permission lets it save your settings locally, and offscreen can help it keep certain background operations alive. The scope is generally in line with what you’d expect from this category of extension.

Tab management tools inherently see a lot about your browsing activity, so a careful user should consider who built the tool. Clones or lookalikes of popular extensions can sometimes appear in stores, and any add-on with this level of access could potentially read sensitive URLs. The developer has declared that data is not sold or used for unrelated purposes, but the publisher identity is the weakest dimension here, meaning there isn't much publicly verifiable information about who “sauraabhverma39” is. For privacy-sensitive users, that lack of transparency can be a practical concern.

The strongest dimension is Maintenance & Ownership, suggesting the extension is actively updated and has a clear version history, which reduces the risk of an abandoned project being silently turned into something else. Overall, it scores 84.57/100 (grade A), but the lower Publisher & Identity score means you may be placing significant trust in a relatively unknown developer.
