I hit command+\
username and password fields under "Log In" are populated. "Log in" action is performed. I am logged in.
username and password fields under "Log In" are populated. Focus moves to the fields under "Sign Up". "Email address is not valid" appears under the "Sign Up" button. (The extension probably clicked the "sign up" action). I am not logged in.
Not sure this is the proper forum to report this.
