According to Microsoft “It is a secure web browser constructed as a multi-principal OS”. In today’s world websites are dynamic web applications composing data from many websites. So a perfect web browser should support multi principle operating environment with shared resources from different website principals but any existing browser do not have a multi principal operating system with which a browser can have an exclusive control to protect the system resources among website principal. For this a secure web browser Gazelle is constructed as a multi principal OS.

Gazelle is supposed to do the legacy protection of cross-origin script source, and cross-principal, cross-process display and events protection and it is not going to replace Internet Explorer. It uses its actual tendering technology from Internet Explorer so till now Gazelle is a prototype as it have many difficulties such as it runs slow then Internet Explorer specially while opening new website.
