This extension adds `rel="noopener noreferrer" to any links which are external links or defined with target '_blank'. This improves the security of the site:

  • noopener: Instructs the browser to open the link without granting the new browsing context access to the document that opened it — by not setting the Window.opener property on the opened window (it returns null).
  • noreferrer: Prevents the browser, when navigating to another page, to send this page address, or any other value, as referrer via the Referer: HTTP header.


  1. Get the extension by using composer composer require georgringer/noopener
  2. Install the extension.
  3. Done


  • TYPO3 LTS 8.7 or 9.5

TYPO3 10.1 will ship with such setting by default!
