> Could you give a brief explanation of the technical implementation - how does this extension poll the site for notifications? Does it keep the session constantly online, or does the pluging check-in to the site periodically for new notfications?

It gets some user data at boot, for example to get the user id.  
Then it uses message bus to receive notifications.  
@sam gave me the advice in this [post](https://meta.discourse.org/t/discourse-chrome-extension-to-show-unread-count/27853/12)
