Microsoft Edge is undergoing a user interface overhaul, with new builds from the Edge Canary and Dev Channel showcasing a design inspired by Microsoft's Copilot app. The refresh includes updates to context menus, the new tab page, and settings, featuring rounded corners and a color palette consistent with Copilot. Users can toggle Copilot Mode on or off, affecting the content displayed on the New Tab Page. There are also discussions about an AI-enhanced version of MSN.com, potentially called "Ruby." The new design is currently in testing and will be rolled out in phases. Feedback from users will influence future design iterations.
