This is caused by your Anti-Virus program, most of the time. You may also need to update Firefox. Please see What do the security warning codes mean?.

But how do I get it working again? That article didn't really help, and I dont need to update firefox...?
Hi !
Like Andrew already indicated: this is most likely caused by an Antivirus program.
If you have such a program installed (like e.g.   Kaspersky or Avast): disable it and see if the problem goes away.
