I don't know what do you mean by "safe". What is Firefox doing or not doing that you want to change?

I need to add a trusted site (url)

But "trusted" in what respect? Are you getting errors related to the site's SSL certificate? Does the site need to install Firefox extensions? Or does it need to bypass the pop-up blocker? Do you want Firefox to pass through Windows credentials?

Unlike zones in IE, these are all separate issues in Firefox.

There shouldn't be the need to add a security exception and you should never add a permanent exception.

There is security software like Avast and Kaspersky and BitDefender and ESET that intercept secure connections and send their own certificate.

If you can't inspect the certificate via "I Understand the Risks" then try this:

Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:

• chrome://pippki/content/exceptionDialog.xul

In the location field of this window type or paste the URL of the website.

• retrieve the certificate via the "Get certificate" button
• click the "View..." button to inspect the certificate in the Certificate Viewer

You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then you can attach a screenshot that shows the certificate viewer.

It would be easier if you describe what isn't working the way you want it to work.

Ok no worries Please see screenshot attached

I think that you would have to add this certificate to the Citrix database.
