Answer 1

After seeing your comments I think this might suite your needs. It works by getting the pages source, render it to a dom, disable all the js and then put it back into the page. Not exactly what you wanted but should suite your case well...

mainfest.json

{
  "name": "Reload and Kill JS - Using a content script",
  "version": "1.0",
  "permissions": [
    "tabs", "" , "storage"
  ],
  "background": {
    "scripts": ["background.js"]
  },
   "content_scripts": [
    {
      "matches": [""],
      "js": ["injectedCode.js"],
      "run_at" : "document_start"
    }
  ],
  "minimum_chrome_version" : "20",
  "manifest_version" : 2
}

background.js

chrome.storage.local.set({"blockhttp://paez.kodingen.com/":true});

injectedCode.js

reloadAndKillJS = function() {
    document.documentElement.innerHTML = 'Reloading Page...';

    var xhr = new XMLHttpRequest();

    xhr.open('GET', window.location.href, true);

    xhr.onerror = function() {
        document.documentElement.innerHTML = 'Error getting Page';
    }

    xhr.onload = function() {
        var page = document.implementation.createHTMLDocument("");
        page.documentElement.innerHTML = this.responseText;

        var newPage = document.importNode(page.documentElement, true);

        var nodeList = newPage.querySelectorAll('script');
        for (var i = 0; i < nodeList.length; ++i) {
            var node = nodeList[i];
            if (node.src) {
                node.setAttribute('original-src', node.src);
                node.removeAttribute('src');
            }
            node.innerText = '';
        }

        document.replaceChild(newPage, document.documentElement);
        delete page;

        // Do your thing here
    }

    xhr.send();
}

chrome.storage.local.get("block"+window.location.href,function(items){
    if (items["block"+window.location.href]){
    window.stop();
    reloadAndKillJS();  
    }
});
