Ist diese Website wirklich von Firefox?

Hello JustSecurity,

Nein !

It's a scam;   please ignore !

Like posted above, Mozilla never offers a reward and would never ask you to enter a credit card number or other personal data in a survey or otherwise. Don't let the presence of the Firefox logo mislead you.

If you get a pop-up message asking to update Firefox or plugins or scanning for malware or offering a reward then such a message is likely a scam and you should NEVER respond to such an alert to avoid getting infected with malware.

• only update Firefox via "Help -> About" or by downloading and installing Firefox from the Mozilla and never via a pop-up or link on a web page.
• plugins should only be updated via the plugin itself or by visiting the home page of the plugin.
