Features & Capabilities

The showModalDialog Shim Chrome extension enables legacy enterprise web applications that rely on the deprecated showModalDialog() method to function properly in modern browsers. It works by rewriting calls to showModalDialog() to use the window.open() function instead, ensuring compatibility where showModalDialog() is no longer supported.

Ported from the original Chrome version available on GitHub, this extension provides a seamless solution for users needing legacy modal dialog support without modifying the underlying application code. It's the perfect tool to maintain enterprise workflows on up-to-date browser environments.
