Can you view the headers in the email with out opening it, does it come with a attachment. What are you viewing it in or on, what is the subject title, always provide as much information as possible so that we can assist you. ? I would think to question it myself if you were not expecting a email from us. Did you sign up for the newsletter ? https://blog.mozilla.org/internetcitizen/author/mjkellymozilla-com/ so yes there is a MJ Kelly but is up to you, do a virus scan on if you can, I would not know as you have to give us more information

Thanks for your help and quick response. Somehow, I went from being an early adopter (I bought my 1st computer - a TRS 80 in '79 or '80) to a dinosaur nowadays so I really appreciate your thorough answer.

Your info helped me ascertain the email was the real deal.
