Unfortunately you fell victim to a scam survey that was stealing the Mozilla and Firefox logos to appear legitimate. Mozilla does run surveys of users, but they collect very little personal information (if any) and they would never be entering you for a raffle. I'd suggest the following: * Run a full scan of your computer using www.malwarebytes.com to ensure you didn't pick up malware * Make sure you don't have any add-ons you don't recognize installed * Don't respond to the spam e-mails you're receiving. Simply send them to your junk e-mail folder. * It's probably a good idea to change your e-mail password as well * Finally, I'd suggest signing up for monitor.firefox.com to ensure your e-mail address isn't in any data breaches (it will also notify you in the future of new breaches) * Finally, and this has nothing to do with the scam survey, but I'd suggest trying to update your MacOS software. You're on a pretty old version
