# Deprecation: #83964 - EXT:form - streamline usage of icons {#deprecation-83964}

See [forge#83964](https://forge.typo3.org/issues/83964)

## Description {#description}

With issue #82348 EXT:form icons have been cloned into `EXT:core/Resources/Public/Icons/T3Icons/form`.
Icons are now available with the identifier prefix `form-` (previously `t3-form-icon-`).
For this reason, the old icon identifiers with `t3-form-icon-` prefix have been marked as deprecated and will be
removed in TYPO3v10.

## Impact {#impact}

Usage of the following icon identifiers will trigger a deprecation warning:

-   `t3-form-icon-advanced-password`
-   `t3-form-icon-checkbox`
-   `t3-form-icon-content-element`
-   `t3-form-icon-date-picker`
-   `t3-form-icon-duplicate`
-   `t3-form-icon-email`
-   `t3-form-icon-fieldset`

-   `t3-form-icon-gridcontainer`
-   `t3-form-icon-gridrow`
-   `t3-form-icon-hidden`
-   `t3-form-icon-image-upload`
-   `t3-form-icon-insert-after`
-   `t3-form-icon-insert-in`
-   `t3-form-icon-multi-checkbox`
-   `t3-form-icon-multi-select`
-   `t3-form-icon-number`
-   `t3-form-icon-page`
-   `t3-form-icon-password`
-   `t3-form-icon-radio-button`
-   `t3-form-icon-single-select`
-   `t3-form-icon-static-text`
-   `t3-form-icon-summary-page`
-   `t3-form-icon-telephone`
-   `t3-form-icon-text`
-   `t3-form-icon-textarea`
