New Microsoft Edge Nightly build adds new user interface for Clear Browsing Data function. Clear browsing data function by default will clear browsing history, cookies and site data. New user interface makes it easier for more causal users to see all available options and select those that they want to clear. The new interface also adds a blue button that is first thing a user see when they go into the Privacy and services section. To enable the new interface, you need to enable an experimental flag in the edge://flags screen.
