Having worked with Credit, Debit and Gift Card processors they have security in place to make any gift card number void if it is ever had the balance checked before the card is activated. Also the online balance check would require the four digit security code which is random and only known to the processor. This might only work if a retail company was using an in-house card program and didn't implement their own security protections.
Yes, You can download the Add-on Compatibility Reporter, it is a Mozilla created add-on, it then shows on the extensions screen if each add-on is compatible with multi-process.
The reason EMV is better is because the chip allows you to sign the transaction datagram before it is sent to the bank. The chip stores the specific cards signing cert and it can't be accessed, every time there is a transaction, the pin pad sends the transaction info to the card which encodes and signs it then it is sent to the processor. NFC and other tap transactions are just as safe because even if you intercept the info you can capture the signing cert and can't duplicate the transaction.
