## Description

The Legacy Browser Support Chrome extension enables enterprises using Windows to seamlessly deploy Firefox while maintaining compatibility with legacy browsers, such as Internet Explorer.

This add-on allows organizations to designate specific URLs to open in alternate browsers through group policy configuration. To ensure proper functionality, users must install the native components available from the official GitHub releases. This solution bridges modern browser deployment with legacy application requirements, helping organizations transition smoothly without losing access to legacy web resources.
