FireFox 43.0.1 installed on XP SP3 system... Cannot go to Google due to "error code: mozilla_pkik_error_not_yet_valid_certificate" Mozilla used to work before update- I CAN go on Bing, Facebook, Ebay..ect.., There are other sites I cannot get on- I updated computer's current time and date-
Try to rename the cert8.db file (cert8.db.old) and delete the cert_override.txt file in the Firefox profile folder to remove intermediate certificates and exceptions that Firefox has stored.
If that has 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 previously stored intermediate certificates. Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.
You can use this button to go to the current Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
