Browsing information like history, bookmarked sites, and cookies isn’t accessible to third-party browsers on iOS, and there’s no API to allow this data to be imported. While this is sensitive data, similar import functionality is possible on all major desktop platforms, and iOS is able to mediate access to other sensitive data with user consent (e.g., health and fitness data). Not being able to import data creates significant friction to change from Safari - a user should be allowed to bring their data with them to another browser.
