Why are all google website suddenly giving untrusted certificate warnings in my Firefox v10?

1

Today, I am suddenly getting the untrusted website error for all Google websites, but not for any other. Internet Explorer gives no such error. Reboot of this Windows 7 computer does not help.

Is this some kind of virus infection that is hijacking DNS resolution away from Google to some spoofer?

How can I resolve this issue and get Google websites working again normally?

If I manually enter a Google IP Address, the page loads correctly.

1Did you determine that google IP by normal DNS resolution from your machine? Do you have a tool to check what outgoing connections Firefox makes? – Jonas Heidelberg – 2012-02-07T21:40:05.450

No, I used yahoo to search for an ip address posted on a website. But I also tried doing ping from DOS prompt and tried that address too and it worked fine. What tool allows you to check the outgoing connections from Firefox? – WilliamKF – 2012-02-07T21:43:32.427

do you or your office have a proxy server? – horatio – 2012-02-07T22:17:00.723

I'm using VPN at all times, but now the issue has mysteriously gone away. – WilliamKF – 2012-02-07T22:31:38.373

Another possible reason is an incorrect date (year, for example) on the computer. So browser considers SSL certificates expired or not yet valid.

this would make sense if was occurring in both browsers perhaps but the OP claims it only occurs in Firefox – Mark S. – 2012-02-12T15:33:09.037
