Firefox 8 says a particular secure site is untrusted

[Victor Bien]

I am posting here because there is no answer on mozilla.com support
nor from a couple of other sites offering support. On one page covering
this problem it reports that over 1000 people experience the problem!

The site is my personal superannuation allocated pension site:
https://wrap.beaconinvestment.com.au/cgi-bin/frameset.exe

Oddities at present:
* it only happens when I try to bring it up with my Firefox 8 on a
particular computer;
* I checked with the company and they say their certificate is current;
* if you drill down into the error popup you can confirm the certificate
is current;
* ie tab in said FF also gives the error;
* IE as such works OK;
* Google Chrome works OK;
* Opera works OK;
* Safari works OK;
* On another computer, running Vista, FF works OK.

Finally,
* none of the other https sites - banking, Paypal etc. have this
problem. It affects only this particular site.

This is an annoying problem. I am paranoid about being hacked and
so refuse to bypass the warning preferring to use another browser or the
other computer when I want to have a look at my account.

Any clues here?

The clues would be in the _EXACT_ message you get from Firefox.
What is it? Does it say the certificate is issued for one domain
or subdomain but is being used for a different subdomain? Recent
versions of Firefox may be stricter than other browsers.

On the other computers or in other browser profiles, has that
site and certificate been given an exception some time in the
past? That is one possible reason they other browsers might
allow it.

Thanks.

On the problem XP SP3 computer when I click on the exclamation point
icon and then click the More information button it say:
Owner: This website does not supply ownership information
Verified: not specified and lower down under Technical Details it says
"Connection Not Encrypted".
Now when I click Technical Details inside the popup in the main
panel (under a tab) it says, "wrap.beaconinvestment.com.au uses an
invalid security certificate.
"The certificate is not trusted because the issuer certificate has
expired.
"(Error code: sec_error_expired_issuer_certificate)"

However, now there is a hold up: when I try to logon with Google
Chrome or on the laptop with Firerfox, which still works on this site, I
can't do any more analysis and info gathering until Monday. The site is
closed temporarily for an "update to the platform".

But when the site was still accessible through these other channels
and one looked at the certificate it said "Verified by: Verisign Trust
network" and valid till sometime 2013 and although I can't remember
exactly it did not say the certificate belonged to someone else or to
some other URL!

I'll get back to this if the problem continues - it may go away?

Well the site it back up; it works correctly with (say) Google
Chrome, the certificate information is what I expect. However, when I
use my Firefox on my XP computer it still says what I noted above. It's
too awkward to look see how the Firefox on my Vista laptop behaves but I
expect it would work correctly.
