www.google.com uses an invalid security certificate, Error code: SEC_ERROR_UNKNOWN_ISSUER
After I upgrade my laptop to win10, I cannot access google(so as youtube, be can access many other websites) any more with firefox, but chrome and ie are OK.
The error is as below: Your connection is not secure The owner of www.youtube.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website. This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate. www.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER

Should update check McAfee forum to see if they have any issues going on.
uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :
- https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
- https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer
Reinstall with Current Release Firefox 57.0.3 with a Full Version Installer

If the certificate is not trusted because no issuer chain was provided (SEC_ERROR_UNKNOWN_ISSUER) then click the blue error message to expand this section and show the certificate chain. You can click "Copy text to clipboard" and paste this base64 encoded certificate chain text in a reply. That will allow us to details like the issuer of the certificate.
- always be cautious when you get an 'Untrusted' error message
- never create a permanent exception without investigating the cause and only use this to inspect the certificate

Hi, I still cannot access google.com after reinstall firefox based on Pkshadow's comments, but it shows Certificate chain now while previously Certificate chain is empty.
The error message and Certificate chain is as below:
https://www.google.com/?gws_rd=ssl

Thank you for the certificate data. The site certificate was issued by
"EMC SSL Decryption Authority"
which is not the issuer of the genuine certificate. So what is EMC doing in there? I really don't know. Is this a business network?
I found a reference to an EMC certificate here, but it does not seem applicable to websites, so I wouldn't install this until you figure out what's going on:

Hi, jscher2000
After I export certificate from my IE, I import it to my firefox failed with error "The personal certificate can't be installed because you do not own the corresponding private key which was created when the certificate requested" but when i export certificate from my IE, it cannot export private key.
You can try to set this pref to true on the about:config page to import the certificates from the Windows certificate store to see if that works.
- security.enterprise_roots.enabled = true
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

You need to import the certificate to the "Authorities" tab. The kind of certificates you can import to the "Your Certificates" tab are quite different.
Thank you all,
I can access google.com now with firefox after I import EMC SSL certificate to Firefox from IE.
