chrome extension multiple tabs and chrome.runtime.connect

I am opening a long-lived connection with background from a content script if the url is test.com. I am using chrome.runtime.connect. But if I open multiple tabs with test.com, I am getting multiple onMessage calls from the background script.

The question is that the content scripts are not shared with multiple tabs but how come the ports?

It is by design, since if you didn't call runtime.Port.disconnect, the previous connection will be maintained and every time you open a new tab with test.com, you content script is loaded and starts to establish another long-lived connection.

You could call runtime.Port.disconnect to cut the current connection when a new tab is created, or you may distinguish different connections by Port, you can access port.MessageSender on runtime.onConnect.addListener(function(port){});, which contains tab as unique info for the sender.
