I did try to sign up for Firefox on a Mac. I saw the email with a confirmation code that indicated will expire in 15 min. But I saw it over 24 hours after it was sent because I didn't check the mail that day. I didn't address the issue because of the expiration. Today I got an email: {Welcome to Firefox! A few days ago you created a Firefox account, but never confirmed it. Please confirm your account in the next 15 days or it will be automatically deleted. Don’t miss out on the browser that puts you and your privacy first.} Of course I confirmed it, and I don't know if that was stupid or not. What I'm asking: is this a confirmation to use Firefox on the Mac (all updates complete). Thanks a bunch. L V Jones Raleigh, NC
