Chrome extension that enables chatting with users on same page : <p>I've seen Chrome extensions that claim to do such thing, but the chat page they provide are all separate page from the original web page, which is really inconvenient. Is there existing plugin that can do this? I may want to build one myself but I'm guessing there may be some permission issue, since that would be showing content from 3rd party.</p>

<p>Is it possible to insert content like a chat box into all different web pages using Chrome extension?</p>
