About Yahoo Mail UI Enhancer

Enhance your supported Yahoo Mail workspace with focused, privacy-first visual improvements. Yahoo Mail UI Enhancer hides the Mail Sidebar to create more room for your inbox and reading workspace while keeping a comfortable content gutter. In dark mode, it makes unread messages easier to spot without changing Yahoo Mail’s native unread indicator or interaction states. Use the toolbar popup to control Sidebar Concealment and Unread Emphasis, and see the current page status at a glance. Your preferences stay on your device: the extension makes no network requests and includes no telemetry, analytics, or tracking. This is an independent, unofficial extension and is not affiliated with, endorsed by, or sponsored by Yahoo.
