I am trying to create an extension to analyse requests made on the chrome browser but I can't put it work. The alert never fires.

manifest.json

{

  name: Test,

  description: Test,

  version: 1.0,

  manifest_version: 2,

  permissions: [background, tabs, webRequest, webRequestBlocking, *://*/*],    

  background: {

    scripts: [background.js],

    persistent: true

  }  

}

background.js

var callback = function(details) {

    alert(hello);

};

var filter = { *://*/* };

var opt_extraInfoSpec = [];



chrome.webRequest.onBeforeRequest.addListener(

        callback, filter, opt_extraInfoSpec);

Why is it my alert not firing?

Your filter is the wrong format - it's not a valid object at all. Addtionally it needs to contain at least the 'url' property. If you wan't all URL's, use this:

var filter = {urls: [<all_urls>]};

Check out this for exact details on the format for the filter: https://developer.chrome.com/extensions/webRequest#type-RequestFilter
