787733 - Invalid SSL certificate prevents access to website

Status: RESOLVED DUPLICATE of bug 659736

(Firefox :: Untriaged, defect)

Description

[Francois W]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:15.0) Gecko/20100101 Firefox/15.0
Build ID: 20120825202003

Steps to reproduce:

When I go to https://coa.inducks.org I am rightfully told that the certificate is invalid

coa.inducks.org uses an invalid security certificate.
The certificate expired on 09/01/12 04:01. The current time is 09/02/12 00:11.
(Error code: sec_error_expired_certificate)

when I click on "Add exception..."  I am told that the certificate is valid and can not add it to the exception list no matter what I do. As a result I can not access to the website.

I am using Firefox 15.

It is possible that I am using a cookie that slighlty change the behavior of coa.inducks.org, however I can make any further test if there's a need to.

Actual results:

As I wrote I can not access the website.


Expected results:

The "Exception..." dialog box should recognize that the certificate is invalid and let me add an exception if I want to.

It seems the bug was not reproducable because users without some specific cookies that I had were redirected to the http version of coa.inducks.org.
I have now changed the website so that after cleaning all cookies the same problem appears.
Let's see if someone can reproduce the problem.

On Windows 7 I get the proper Dialog as shown in the Attachment.

Adding an exception works fine with Seamonkey trunk on win7.

I got the same problem on another machine with Firefox 14.0 and Linux Mint.
However the problem disappear when I move ~/.mozilla/firefox somewhere and restart Firefox.
I guess the problem appears when someone has visited the website at a time where the certificate was valid.
It will however be much more complicate to reproduce the bug.
Thanks anyway.
