Really, we don’t know where the technology goes, how we wonder what is it ! Firefox is now compatible with a new addon called Chicago Bus Tracker. It lets you pick several CTA bus routes to be notified of any service bulletins. At the same time, it shows you the bus stop arrival times for any number of chosen stops. All it can be done, with a click on the status bar icon.

Moreover, the mobile version shows bus stop arrival time and gives service bulletins when asked for monitored bus stops and operates with caching to reduce the network traffic.
