Please use a global handler instead.

function handleLinkClickOrMouseUp(e) {
  var el = e.target;
  if (el.nodeType == Node.ELEMENT_NODE &&
      el.webkitMatchesSelector('A, A *')) {
    while (el.tagName != 'A') {
      el = el.parentElement;
    }
    if (el.protocol == 'file:' || el.protocol == 'about:') {
      chrome.send('navigateToUrl', [el.href, e.button, e.shiftKey, e.ctrlKey,
          e.altKey, e.metaKey]);
      e.preventDefault();
    }
  }
}

document.addEventListener('click', handleLinkClickOrMouseUp, true);
document.addEventListener('mouseup', handleLinkClickOrMouseUp, true);


This way we do not need to manually call handleFileOrAboutLinkClicks on the
links we care about. This also ensures we do not duplicate the code.

+  // Handle left clicks.
+  link.onclick = function(event) {
+    if (link.href.search('file:') == 0 ||
+        link.href.search('about:') == 0) {
+      chrome.send('navigateToUrl', [link.href, '0']);
+      return false;
+    }
+  };
+
+  // Handle middle clicks.
+  link.onmouseup = function(event) {
+    if (event.button == 1 &&
+        (link.href.search('file:') == 0 ||
+        link.href.search('about:') == 0)) {
+      chrome.send('navigateToUrl', [link.href, '1']);
+      return false;
+    }
+  };
+}
