# Deprecation: #86178 - Class ElementBrowserFramesetController {#deprecation-86178}

See [forge#86178](https://forge.typo3.org/issues/86178)

## Description {#description}

Class `\TYPO3\CMS\Recordlist\Controller\ElementBrowserFramesetController` and the route
target of `browser` have been marked as deprecated and should not be used any longer.

## Impact {#impact}

If calling that controller class a PHP `E_USER_DEPRECATED` error is triggered.

## Affected Installations {#affected-installations}

The route target is unused in core for a while already. Extensions are only affected
if they call the Backend route target `browser` that renders the element browser
in a frameset.

## Migration {#migration}

Use the modal based element browser with the route `wizard_element_browser` instead.
