Attempting to check out a premium account purchase via Paypal, firstly it did a dodgy redirect to some script that seemed to redirect to a DIFFERENT gmail account every time I tried it. On my first try, I got an amount that was way different from what was advertised on their site ($16 which amounted to 13€, instead of the mentioned 9.95€). That raised the first alarm so I went back to clear my cache and retry the Paypal checkout. Then to my surprise, it used a different payment redirect, and another gmail account was supposed to receive the again-increased payment. Unless they got hacked and this is temporary, it seems like very suspicious behaviour and there's no way I would give them my CC details directly.

Within one week after buying a premium account with a VISA-Card, the bank locked the card. Reason: It was tried to withdraw money with the card-number in Hotels. There where no other buyings with the card this year. Either Fireget acts on purpose or they have a security problem. My advice: Dont use your credit card to pay for a premium account. Update: The PC that was used to pay was scanned with Anti-Virus- and Anti-Trojan-Software. No result. I dont want to blame Fireget - maybe the leak of the VISA-Card can be found somewhere else - just be careful!
