  // - storage/default/https+++foo.bar.mozilla-iot.org
  // - create_db.js
  // - storage.sqlite
  // The file create_db.js in the package was run locally, specifically it was

  //   mach xpcshell-test --interactive dom/localstorage/test/unit/create_db.js
  // Note: to make it become the profile in the test, additional manual steps
  // are needed.
  // 1. Manually change the group in .metadata and .metadata-v2 from
  //    "bar.mozilla-iot.org" to "mozilla-iot.org".
  // 2. Remove the folder "storage/temporary".
  // 3. Remove the file "storage/ls-archive.sqlite".
