Build a privacy browser around named, isolated sessions rather than one disposable page. Each session can contain multiple tabs, temporary site permissions, selected bookmarks, search preferences, and controlled link routing, while a single action securely destroys the entire session. Start with transparent blocking controls, per-site exceptions, reliable return-to-source behavior, and clear indicators showing what will persist or be erased.

Users increasingly want protection from tracking and unwanted AI search features, but the signals show they will abandon privacy tools that cannot support ordinary multi-page browsing. Continued mobile operating-system changes and in-app webviews make predictable session and link handling more valuable.
