Using the colors of the traffic lights, the extension shows whether everything is in order, or if there are problems. The orange circle appears when the network times out or a potential threat is detected. If the extension detects that the icon does not match, the icon will turn red with an exclamation point. Clicking on the icon should provide more information.
