Legacy Browser Support for IE Mode in Edge

Deploy Microsoft Edge for your organization, but open some sites in an alternative browser.

Legacy Browser Support for IE Mode in Edge is a Chrome extension designed for organizations deploying Microsoft Edge alongside Chrome. It enables seamless automatic switching between Google Chrome and Microsoft Edge in IE mode for sites that require legacy support.

Ideal for businesses relying on a mix of modern and older web applications, this extension allows IT administrators to set policies specifying which sites open in which browser. This facilitates access to web apps dependent on technologies like ActiveX or plugins while maintaining security and performance for modern browsing needs.
