# Feature: #78488 - Add rel="noreferrer" to external links {#feature-78488}

See [forge#78488](https://forge.typo3.org/issues/78488)

## Description {#description}

All links processed by `typolink` with external links opening in a new window have been extended to contain
`rel="noreferrer"`.

Links opening in a new window are defined as those having an attribute `target` which is either not empty,
`_self`, `_top` or `_parent`.

> [!NOTE]
> Initially this feature added `rel="noopener noreferrer`. However `noreferrer` also
> implies the property `noopener`. Therefore, the latter was removed.

## Impact {#impact}

This property improves the security of the site:

-   **`noreferrer`**

    This property prevents the browser, when navigating to another page, to send the page address, or any other value,
    as referrer in according HTTP header. `noreferrer` also implies the property `noopener`, which instructs
    the browser to open the link without granting the new browsing context access to the document that opened it.
