Mozilla Firefox Critical Error is neither the first nor the last misleading notification to be introduced to Mozilla Firefox users online. Notifications like this one are created by schemers who are using them for all kinds of reasons. Some of them could promote links to unreliable websites and installers. Others – and most scam alerts researched in our internal lab are of this kind – introduce users to fictitious helpline numbers, via which schemers could communicate with unsuspecting users. A few other scams include “The Tungsten Rounded Font Was Not Found” fake alert, “Apple Security Breach” fake alert, and “Your Apple Device Has A Virus” scam.

According to the message following this error notification, your personal logins and bank information are at risk, and while that might be true, that is not due to the malware that is introduced to you via the scam. In fact, the fictitious notification does not reveal the name of the malware, which is a signal that you are being scammed. Another sign you cannot ignore is the URL of the page representing the fictitious alert. Real security warnings are never shown via random, unfamiliar pages, and you should only trust alerts that are shown by trusted security software that is installed on your PC, as well as your operating system.
