# Disable Plugins

> important As of **2026 Q1 SP2**, the legacy **IFrame**, **Silverlight** and **Flash** modules have been removed from the source code. This change improves the compatibility with modern browsers and hardens the security of the RadAsyncUpload control. The `DisablePlugins` property no longer exists and any references to it should be removed from your code.
