If you used HTML5 hidden property:

$('enabledMode').hidden = !enabled;
$('disabledMode').hidden = enabled;

+    $('enabledMode').classList.remove('hidden');
+    $('disabledMode').classList.add('hidden');
+  } else {
+    $('enabledMode').classList.add('hidden');
+    $('disabledMode').classList.remove('hidden');
+    return;
+  }
+
+  // Clear any previous list.
+  crashSection.innerHTML = '';

I prefer textContent = '' but no big deal.

+
+  for (var i = 0; i < crashes.length; i++) {
+    var crash = crashes[i];
+
+    var crashBlock = document.createElement('div');

An alternative might have been to put this as markup in the original HTML inside
a display none div. Then you could have grabbed it and cloned it and modified
the text.

In this case the dom is relatively small so it is easy enough to manage.

+    var title = document.createElement('h3');
+    title.textContent = localStrings.getStringF('crashHeaderFormat',
+                                                crash['id']);
+    crashBlock.appendChild(title);
+    var date = document.createElement('p');
+    date.textContent = localStrings.getStringF('crashTimeFormat',
+                                               crash['time']);
+    crashBlock.appendChild(date);
+    var linkBlock = document.createElement('p');
+    var link = document.createElement('a');
+    link.href = 'http://code.google.com/p/chromium/issues/entry?' +
+        'comment=URL%20(if%20applicable)%20where%20crash%20occurred:%20%0A%0A' +
+        'What%20steps%20will%20reproduce%20this%20crash?%0A1.%0A2.%0A3.%0A%0A' +
+        '****DO%20NOT%20CHANGE%20BELOW%20THIS%20LINE****%0Areport_id:' +
+        crash['id'];
+    link.target = '_blank';
+    link.textContent = localStrings.getString('bugLinkText');
+    linkBlock.appendChild(link);
+    crashBlock.appendChild(linkBlock);
+    crashSection.appendChild(crashBlock);
+  }
+
+  if (crashes.length == 0)
+    $('noCrashes').classList.remove('hidden');
+  else
+    $('noCrashes').classList.add('hidden');
+}
+
+document.addEventListener('DOMContentLoaded', requestCrashes);
