You have received an invalid certificate. Please contact the server administrator or emailcorrespondent and give them the following information:
Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.
(Error code: sec_error_reused_issuer_and_serial)
The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
* Please contact the web site owners to inform them of this problem.
If you have recieved this error and are trying to access something that has a self signed certificate, there are two places in Firefox that you must visit in order to access the particular site again.
The first visit Tools–> options–>Advanced–>View Certificates
You must remove the certificates in the “Servers” tab, then under the same location you must remove the certificate authority because it is a self signed certificate, so on the “Authorities” tab, simply find the CA for the device you are having trouble with and delete it.
