I’d love for it to be seamless to switch between browsers. For that, I’d want a common history, bookmarks, cookie store, open windows/tabs, and most importantly, use of the system keychain (on macOS). I’ve never seen anyone talk about trying to effectively sync with a preferred/primary browser. Why isn’t this the goal? Especially for Firefox who’s trying to get people to switch; make it easy! Import isn’t enough, and it still doesn’t use the system keychain.
