  // Some keypoints for the user-agent spoofing.
  // 1. User agent cannot be modified on per website basis, as it will cause
  //    failed verifications on captcha-less web challenge services (which
  //    require the same UA for both the webpage and web worker services)
  //    This is the highest priority as there are many websites depending
  //    on the web challenge.
  // 2. If it will be needed in the future to add some flexibility in the
  //    UA control, then it might be done by changing UA on per-session basis,
  //    in that case both the webpage and the web worker will share the same UA.
  // 3. 'Electron' in the user agent causes "unsupported browser" error on some websites.
  // 4. 'Electron' removal causes issues on some websites (such as google's ones).
  //    For such websites we have to add exceptions and use the original UA.
  // 5. Currently the original UA for the excepted websites is set on per-website
  //    basis. This might break someday (see point 1), in that case consider
  //    implementing the UA change on per-session basis (see point 2).
