TYPO3 Extension noopener
========================

[](#typo3-extension-noopener)

This extension adds [`](#id1)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.

Installation
------------

[](#installation)

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

Requirements
------------

[](#requirements)

- TYPO3 LTS 8.7 or 9.5

*TYPO3 10.1 will ship with such setting by default!*
