cannot sign in to a site
Firefox has been my default browser since maybe version 10. Recently I cannot sign in to a frequently used site. It is https://www.kroger.com/signin?redirectUrl=/rx/dashboard . I get the message "We're sorry, an unexpected error occurred. Please try signing in again." I can sign in on Edge and Chrome, both of which I hate. I suspect it has to do with privacy but can't pin down what.
