    <h2>Instructions</h2>
    <p>This page will help debug the JavaScript Error Visualizer extension. Follow these steps:</p>
    <ol>
      <li>Open your browser's developer console (F12 or Ctrl+Shift+I)</li>
      <li>Look for any error messages related to the extension</li>
      <li>Click the "Trigger Test Error" button below</li>
      <li>Check if the extension is capturing and highlighting the error</li>
    </ol>
  </div>

  <button id="error-btn" class="error-btn">Trigger Test Error</button>

  <div class="debug-section">
    <h2>Extension Status</h2>
    <div id="extension-status">Checking extension status...</div>

    <h2>Content Script Check</h2>
    <div id="content-script-check">Checking if content script is loaded...</div>
  </div>

  <script>
    // Function to check if the extension is working
    function checkExtension() {
      const statusElement = document.getElementById('extension-status');
      const contentScriptElement = document.getElementById('content-script-check');

      // Check if window.__JEV_EXTENSION_LOADED__ is defined (we'll add this in our content script)

        statusElement.innerHTML = '<span style="color: green;">✓ Extension detected!</span>';
        contentScriptElement.innerHTML = '<span style="color: green;">✓ Content script is loaded!</span>';
      } else {
        statusElement.innerHTML = '<span style="color: red;">✗ Extension not detected. Make sure it\'s installed and enabled.</span>';
        contentScriptElement.innerHTML = '<span style="color: red;">✗ Content script is not loaded.</span>';

        // Add a global variable that the content script can detect if it loads later
        window.__JEV_DEBUG_PAGE__ = true;
      }
    }

    // Add event listener to the error button
    document.getElementById('error-btn').addEventListener('click', function() {
