nit: You ran git cl format right?

Yes, I ran it. I've now added a "using content::NavigationHandle" so that it
fits in 2 lines instead of 3.

+    content::NavigationHandle* handle) {
+  DCHECK_CURRENTLY_ON(BrowserThread::UI);
+
+  if (!handle->HasUserGesture())
+    return nullptr;
+
+  if (handle->GetURL().GetContent().compare(0, strlen(kFlashDownloadURL),
+                                            kFlashDownloadURL)) {
+    return nullptr;
+  }
+
+  return base::MakeUnique<navigation_interception::InterceptNavigationThrottle>(
+      handle, base::Bind(&ShouldInterceptNavigation), true);
+}
