Is CityU Quick Course Adder safe?

Low risk

CityU Quick Course Adder loads its popup stylesheet from jsDelivr when the extension popup opens.

When you open the extension popup, your browser requests a Bootstrap stylesheet from cdn.jsdelivr.net, revealing that popup use to the CDN. The CRNs entered in the popup are stored in Chrome local storage and filled into CityU registration pages; the confirmed network recipient is jsDelivr for the stylesheet request.
