Facebook send me a browser message when i get a new message or friends request.
Facebook can do it even when i dont even have facebook opened in a window. Is that some kind of javascript? or browser extension?
I want to archive this on a site of us. If a user uploads a file to another user, the user that recieves the file should get a message. Even if he doenst have the website itself open. I store a remember me cookie on the users PC after they login, so they dont have to login next time.
Can i access that cookie somehow if user doenst have the website openend in a tab?
