Is AdBlock Ninja for Firefox safe?

Clean risk

AdBlock Ninja sends your device location to its servers when you sign in or register in the popup.

When you log in with Google or register inside the popup, the extension reads your browser geolocation (latitude and longitude) and posts it with your account details. Your browser shows a location permission prompt first, and the location is not sent during normal ad blocking.
