title: Chrome extension: Could not load javascript file
body: <p>I have posted another question regarding my Chrome extension <a href="https://stackoverflow.com/questions/28303597/tumblr-dashboard-modifications-per-chrome-extension">here</a>.<br>
  But I have one more question about extensions themselves. I only need a content script for the modification of the Tumblr-Dashboard, no background page or something else, right?</p>
  
  <p>Here is the <code>manifest.json</code> file:</p>
  
  <pre class="lang-js prettyprint-override"><code>{
      "name": "Tumblr - Tiled Dashboard",
      "version": "0.0.54",
      "manifest_version": 2,
      "description": "This extension modifies the look of your Tumblr dashboard.",
      "icons": {
          "16": "images/icon_16.png",
          "48": "images/icon_48.png",
          "128": "images/icon_128.png"
      },
      "content_scripts": [
          {
              "matches": [ "*://*.tumblr.com/dashboard" ],
              "css": [ "styles.css" ],
              "js": [ "jquery-2.1.3.min.js", "masonry.min.js", "code.js" ]
          }
      ],
      "homepage_url": "mypage",
      "author":  "myname"
  }
  </code></pre>
  
  <p>To start, I ask if this is alright? I have read a lot about the <code>manifest.json</code> file and everything seems to work fine when I try out the extension locally. But when I pack the extension and upload it, there are two problems:</p>
  
  <ol>
  <li>I cannot find the extension when I search for it</li>
  <li>When I use the link to find the extension, and I want to install it (tried that on 2 different PCs), I get an error, telling me that the <code>jquery-2.1.3.min.js</code> file could not be loaded. I therefore changed the order of my JavaScript files to test if it was a problem related to the jQuery file, but having <code>masonry.min.js</code> as the first file in the array resulted in the same error.</li>
  </ol>
  
  <p>Why does this happen? Is the <code>manifest.json</code> file ok? Do I need some special permissions?</p>
  
  <p><strong>Edit:</strong>
  This is a screenshot of when I try to install the extension from the Chrome Web Store (where I also can't find it by search).</p>
