I saw a youtube video of how to create a basic chrome extension and i loaded unpacked extension into the browser successfully but it does't give any popup.Here is the code
{
"name":"Facebook",
"version":"1.0",
"description":"My Facebook Profile",
"manifest_version":2,
"browser_action":{
"default_icon":"google-plus-red-128.png",
"popup":"hello.html"
}
}
and here is the html file
<h2>hello world</h2>
