Do you know what Mozilla Firefox Critical Error is?
Mozilla Firefox Critical Error might look rather convincing, but you should know it is not a genuine error, and therefore, it comes not from your browser or the computer’s operating system. Our computer security specialists report the fake alert could appear after visiting unreliable web pages related to the scam or if the user installs unreliable software that distributes pop-ups or other ads leading to the threat’s website. If you encountered this threat, we would advise you to get to know it better. Once you read our text and learn what Mozilla Firefox Critical Error might do or how it could be dangerous, we recommend using the instructions located at the end of the text. They will explain how to reset the affected browser, how to remove potentially dangerous applications from the system, and what to do to close the browser showing the fake alert if you cannot get rid of it.
To start with, it would be useful to know how Mozilla Firefox Critical Error could enter one’s system and how to avoid such threats in the future. As we mentioned in the beginning the user might be redirected to the fake alert’s website (0x00381136100.bid) after visiting questionable web pages and interacting with any content on them. Moreover, the advertisements promoting the scam could be displayed by some unreliable application that the user may have installed unknowingly or accidentally, for example, it might be an adware application. This case is more likely to be if you have noticed more doubtful advertisements lately and you have no idea where they come from. Naturally, the best course of action would be to check recently downloaded programs and erase ones that might be potentially dangerous.
Clearly, this particular fake alert is targeted only at Mozilla Firefox users. Our computer security specialists say at first the user should get redirected to the scam’s website where they might see a message claiming some hackers tried to steal sensitive data, get access to the system, harm the computer, and so on. Soon the user should see a fake Authentication Required pop-up asking to enter a correct password and suggesting calling a toll-free telephone number (+1 (877) 556-6888). Unfortunately, inserting any password will not solve the non-existent problem or close Mozilla Firefox Critical Error. However, our researchers say one could close it by just closing the browser or if needed killing its process through the Task Manager. We highly recommend doing so instead of calling the provided telephone number, because if you do call it, the fake alert’s creators might try to trick you into purchasing tools or services you do not need, persuade you to reveal your sensitive data, or suggest doing something else that could cause you trouble.
Users who find it challenging to close Mozilla Firefox Critical Error or keep seeing it reappearing on their browsers should take particular steps to ensure it does not come back. Those who would like to deal with the threat manually could follow the removal guide available at the end of this article, but if the given tasks appear to be too complicated or you fear you may not be able to clean up the system properly, we would recommend employing a reputable antimalware tool instead.

In non-techie terms:
Mozilla Firefox Critical Error is a fake system alert that might lie to the user about some hackers attacking his system and trying to steal his personal data. Then the scam website should show a fake Authentication Required window, which is why even the correct password would not fit and accordingly some users may feel they have no other choice but to call the provided telephone number (+1 (877) 556-6888). Needless to say, we highly advise you not to do this, because the people you may contact could try to scam you by selling various services or products you do not need or gain access to the computer. Either way, the consequences could be severe, and if you do not want to experience them, we urge you to erase Mozilla Firefox Critical Error right away. To do so manually we suggest using the removal guide available a bit above, but if it looks too complicated, it might be best to leave this task to a reputable antimalware tool.
