"The sites says..." This Connection is Untrusted

You have asked Firefox to connect securely to addons.mozilla.org, 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.

Technical Details

addons.mozilla.org uses an invalid security certificate.

The certificate expired on 8/21/2011 4:59 PM.

(Error code: sec_error_expired_certificate)


I Understand the Risks
