Firefox does not recognize Google certificate, other browsers do.
Can't get it to work. Have recently reinstalled Firefox, it worked fine before.

Check out why the site is untrusted (click "Technical Details to expand that section) and if this is caused by a missing intermediate certificate then see if you can install this intermediate certificate from another source.
You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
- Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
- Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
You can see more Details like intermediate certificates that are used in the Details pane.
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".
Note that some firewalls monitor secure (https) connections and send their own certificate instead of the website's certificate.
Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.

When I use my company VPN, I cannot access Google. How can I make an exception for my company VPN?
You would have to install the root certificate.
Firefox uses its own certificate storage while IE and Google Chrome use the Windows certificate storage, so you can try to export that certificate from other browser if it has been installed for them and import this root certificate in the Firefox Certificate Manager.
You need to set trust bit to make the certificate work as a trusted root certificate (intermediate certificate should never have trust bits set).
I am not able to find the cert in Chrome or IE. Can you point me to the right directory/path?

If you open a connection to a page that (possibly) uses this certificate then you can inspect the certificate chain by clicking the padlock on the location bar in Google Chrome (Connection > Certificate information > Details). I'm on Linux and don't know the details for IE, but I assume that it is something similar.
