Re: [crx] hello,how to send messages from background to popup in chrome extesion?

Generally, you do not have to use message passing.

I am not sure whether this is a best practice, though, but you can use chrome.extension.getViews({"type": "popup"}), which returns a window and do whatever you want with it. In reverse, use chrome.extension.getBackgroundPage().

If you still want to use message passing, either chrome.extension.sendMessage or chrome.extension.connect sound like viable solutions. All of the active extension pages (popups, tabs, whatever) will get the message passed by sendMessage, like the documentation states.
