We want to be able to communicate seamlessly between different parts of our application regardless if that part lives within the background page, content script, action popup, etc. To do this we had created an abstraction around ports. There is an object that lives in the background page and listens to incoming port connections. When a message is received it then retransmits it to all the other ports. This allow us to send a message and any other part that may be interested can listen for that message. This doesn't work now.
Take for an example the user changes the location they want to see weather data for. The content script picks this up and sends out a message. There maybe a part in the action popup that listens to this message and changes the selected location UI to reflect the change. There may also be several parts in the background that listen for this message and update the weather feed, update the datastore, etc...
