# Breaking: #84843 - Use no-cookie domain for youtube by default {#breaking-84843-1668719171}

See [forge#84843](https://forge.typo3.org/issues/84843)

## Description {#description}

To improve the privacy of users the renderer for YouTube videos has been changed to use
the no-cookie domain `www.youtube-nocookie.com` by default. The regular domain `www.youtube.com`
is used if explicitly set by the following TypoScript configuration:

```typoscript
lib.contentElement {
    settings {
        media {
            additionalConfig {
                no-cookie = 0
            }
        }
    }
}
```

## Impact {#impact}

The TypoScript configuration `lib.contentElement.settings.media.additionalConfig` is used
as attribute `additionalConfig` of the ViewHelper `\TYPO3\CMS\Fluid\ViewHelpers\MediaViewHelper`.

If no configuration is provided, the domain `www.youtube-nocookie.com` is used.

## Affected Installations {#affected-installations}

Installations which require the usage of the domain `www.youtube.com` or setting cookies by YouTube.

## Migration {#migration}

Use the TypoScript configuration `lib.contentElement.settings.media.additionalConfig.no-cookie = 0`
