<ul><li>Click the link at the bottom of the error page: "I Understand the Risks"
</li></ul>
<p>Let Firefox retrieve the certificate: "Add Exception" -&gt; "Get Certificate".
</p>
<ul><li>Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
</li></ul>
<p>You can see more Details like intermediate certificates that are used in the Details pane.
</p><p>If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
</p><p>Note that some firewalls monitor secure (https) connections and send their own certificate instead of the website's certificate.
</p><p>Try to rename the cert8.db file in the Firefox profile folder to cert8.db.old or delete the cert8.db file to remove intermediate certificates that Firefox has stored.
</p><p>If that helped to solve the problem then you can remove the renamed cert8.db.old file.
Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previous intermediate certificates.
Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.
</p><p>If that didn't help then remove or rename secmod.db (secmod.db.old) as well.

I meant to actually write it as November and not numerical. I already triple checked the system time and it really is the current date.
So...what's left now?
</p><p>At least I can still open Google, Google+, Google Play &amp; YouTube. So if there was an incoming email, It would show up on the notification.
</p><p>I also find it hard to believe that Gmail &amp; Yahoo Mail would have an expired certificate at the date around the present time. though maybe that isn't the issue.

But I'll try it as a test anyway.
As for the system's date &amp; time; unless the current date &amp; time in reality as shown in my system clock setting is not 28/10/2013, 02:10 AM, GMT +07:00, Give or take marginal error in minutes then, no. My system clock is as should be as I stated previously. Thanks.
