Firefox keeps refusing me access to websites (including this one) and gives me a message that the site is being blocked or cannot be accessed because the "security certificate cannot be verified". Could this be due to a virus? I have tried updating the Firefox browser and have tried deleting and reloading all of my browser add-ons and keep getting the same failure to access websites. Firefox also gives me intermittent messages that my internet connection has failed. I have used Firefox with good results for many years but am very frustrated and am about to stop using Firefox. I recently tried to put a message on a Funeral website to a close friend for her mothers service when I was unable to attend the service at the gravesite or at the funeral home and kept getting this same message and disconnected internet message until I had to give up after several hours composing and trying to send my completed funeral message to the funeral website to my friend because I kept getting this message that the Funeral home's website security certificate "could not be verified". Any suggestions?

Hi SteveT10,

When you go in the site and you get this error, do you eventually have the possibility to add an exception like explained here ?

You should always be cautious when you get an 'Untrusted' error message and never create a permanent exception without investigating the cause and only use this to inspect the certificate.

You can check the date and time and time zone in the clock on your computer: (double) click the clock icon on the Windows Taskbar.

You can click the "Advanced" button on the error page to expand this section and show extra details. You can click the blue error message to expand this section. If the certificate is not trusted (SEC_ERROR_UNKNOWN_ISSUER) then click "Copy text to clipboard" and paste the base64 encoded certificate chain text in a reply. That will allow us to check details like the issuer of the certificate.
