This Connection Is Untrusted
Hi I have a client who has firefox installed on a windows 7 machine and it is getting blocked from attempting to access many reputable websites such as google mail etc. I have tried every potential fix there is and cannot get rid of this error from occuring. I reinstalled firefox, deleted the cert file, cleared the cache/history. I still get blocked when manually typing in websites with https in the address
For some reason I am not offered the "i understand the risk option" to bypass the error. All I see is the "Get me out of here" option
Let me know if there are any other potential fixes.

I figured out the issue. After uninstalling websense there was a registry key that also needed to be deleted. After deleting it firefox can now access all sites
Thanks for your help

This Connection is Untrusted is sometimes caused because the computer system clock is wrong. Check the time / date / time zone settings.
Sounds as though you have saved at least one security exception. Go back to that site and check the issuer of the certificate. You can do that by clicking the padlock icon (or gray warning triangle icon) in the address bar, then More Information, then View Certificate.
Check the "Issued by" and "Certificate Hierarchy" to see whether there is an issuer associated with the client's security software, such as Avast, Kaspersky, ESET or BitDefender. Or something like FiddlerRoot or Sendori which requires an uninstallation and I suggest a malware cleanup.
Thank you both, I believe it is websense that is blocking the connections. We recently rolled it out In our environment
I spoke too soon. I uninstalled websense and it did not resolve the issue. For example I cant get to inbox.google.com under tech details it states it is using an invalid security certificate. The certificate is not trusted because it is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported.

When I try to connect to https://inbox.google.com/ it immediately redirects to https://accounts.google.com/. Due to the redirect, I am not able to inspect the certificate for that first server directly in Firefox.
Have any certificate exceptions been saved on the problem Firefox? If so, please inspect the "Issued by" and "Certificate Hierarchy" information as requested in my earlier reply: https://support.mozilla.org/questions/1078904#answer-770049
To my knowledge no certificate exceptions have been saved. This issue is occurring on multiple machines in our environment which is why I figured websense could have been the culprit since we just rolled it out.
Okay, you could try a site like the following that has an "I understand the risks" section of the error page, expand that, and use the "Add Exception" button to view the certificate. After inspecting that, you can cancel out and not actually add an exception.
