In-depth safety analysis
Sprint Reader requests permissions that allow it to read and display text from the current page (activeTab), add a right-click menu option (contextMenus), read clipboard content (clipboardRead), store settings locally (storage), and detect screen dimensions (system.display).

The system.display permission may help it size the reading area appropriately.
