Hi Alice, I think you are correct that it's a scam.

Very similar variations of this scam have been popping up for the last decade now with the prize claiming to be a current upper end iPhone, Android phone of $1200 or a $1000 gift card from Amazon. Have not seen this scam posted about much over that few years though thankfully. The fact that it asks for credit card for the very cheap $1-2 shipping should be a red flag that all they are trying to do is get your personal information like credit card, email, phone number, address, name and such. I have 6+ screenshots variations of this phone/gift card scam posted about over the years here. Mozilla does do surveys however the site they do it on has always been at qsurvey.mozilla.com and not at some random unrelated to Mozilla site. They may offer some money say as much as $10 for a short survey. Later on the person may get contacted for a hour interview as I have seen compensation of say $150 to $250 for their time after that survey Like for example mentioned in [/questions/1463046] and [/questions/1442740] If by chance Mozilla was giving away a free $1200 phone of $1000 gift card to random people, then they would very likely have you give your personal information on a *.mozilla.org page and not at some random site to keep things legit and secure. A few images below of these fake scams I have seen over the years. As you can see a iPhone X and Samsung S9 were the then so called prizes.
