IE Tab is a browser extension that allows modern web browsers to display web pages using the Internet Explorer rendering engine. It is primarily used to maintain access to legacy web applications and intranet systems that depend on Internet Explorer‑specific technologies. The extension works by integrating the Internet Explorer engine directly into a browser tab, rather than emulating or rewriting page content. This approach ensures compatibility with older technologies such as ActiveX controls, legacy document modes, and proprietary scripting behaviors that are not supported by modern browser engines. IE Tab is commonly deployed in enterprise environments where business‑critical systems cannot be immediately modernized. It provides controlled and configurable access to legacy sites while allowing users to continue using a modern browser for all other web activities.
