Firefox Filters

When I used a link in an email to me (and others like me who had signed up for the service) from the White House staff to access a certain web page, I received the following message in Firefox:


This Connection is Untrusted

You have asked Firefox to connect securely to, but we can't confirm that your connection is secure.

Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

What Should I Do?

If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate. uses an invalid security certificate.

The certificate is only valid for the following names:

(Error code: ssl_error_bad_cert_domain)


How do I go about "instructing" Firefox to allow access to the web site?

It's Not Firefox. It's The Whitehouse Mail Certificate

You'll want to contact the Mail admin and tell them about the problem. My guess is the website they linked to has failed to update their certificate and the WhiteHouse isn't aware of it.

Firefox's ability to tell you about unsecured sites is a "good" thing.

Hope this helps.

Thanks, Grif; a related follow-up

Thanks, Grif, for your reply.

You suggested my contacting Mail administrator.

I use Mozilla Thunderbird's email application. I could not at all find any link for contacting the administrators of Thunderbird. Do you happen to have such a link? (The closest I came to after a Google search was, but that link provides no means to contacting administrators of Thunderbird.)

Thank you very much.

I Think You Misunderstood.. Not Mozilla's Admin...But...

...the individual in the Whitehouse Staff that sent you the link......or the administrator of the website where you were linked to..are the responsible parties. Both of those individuals need to know the link has security issues..

As I stated earlier, I don't think it's Mozilla/Firefox's fault.

Hope this helps.
