Microsoft just killed Edge’s Collections and Sidebar for more Copilot, after years of pushing both features

Microsoft has discontinued Edge's Collections and Sidebar features with the release of Edge 149 on June 4, 2026. Collections allowed users to organize web content, while Sidebar provided quick access to mini web apps. Users are advised to export their data before upgrading to Edge 149 to avoid losing their collections. The removal of these features is part of Microsoft's shift towards focusing on the Copilot feature and AI integration in Edge.
