Install with local filesystem permissions

Chrome Web Store does not allow uploading extensions with "file://*" in the manifest permissions, which prevents previewing patterns on html files hosted on the local filesystem.

Solution

You can get around this by installing the extension manually.

  • Download the extension.
  • Unzip and locate the contents.
  • Modify the portion of the manifest.json file as shown below and save.
    "permissions": [
        "tabs",
        "*://*/*",
        "file://*"
    ]
  • Go to the Chrome Extensions page via chrome://extensions or Wrench Icon -> Tools -> Extensions.
  • Check "Developer Mode".
  • The "Load unpacked extension..." button should appear, click it and locate the extension folder that contains the manifest.json file.

Side Effects

Installing the extension this way will prevent the extension from auto updating through chrome.
