I’ve long thought that a “security health check” would be a killer feature for a browser, along with a “do one thing” button. A Firefox-monitor-plus idea, a password manager that could warn you about compromise, weakness or re-use and rather than throwing up alerts, offer you a clean path to take one action to improve your situation and an option to schedule a nudge to do a second in a little while.
