Microsoft Edge has introduced WebUI 2.0, a new framework that improves the browser's speed and responsiveness by addressing performance issues related to JavaScript and code sharing. The migration to WebUI 2.0 is ongoing, with some settings already transitioned. The Browser Essentials feature now loads 42% faster, and the Favorites bar has a 40% increase in loading speed. The msInlineComposeWebUI feature has significantly reduced loading time, allowing the Copilot compose box to open almost instantly. The msPdfWebui2 feature also shows improved launch speed. Microsoft is gradually integrating these components into Edge, with many still not in the stable version. The company is seeking user feedback for future updates and is experimenting with methods to streamline the user experience by decluttering the interface.
