Certificate problem with Firefox 4.01 and Windows 7 (Win XP is working fine)
When I try to connect to an https page with a valid certificate, Firefox 4 shows me "sec_error_bad_signature" error message... but only in Windows 7 OS. If I try the same in a Windows XP it works correctly. Any suggestions?

You may have an expired VeriSign (VeriSign, Inc.) certificate.
You can check that in the Certificate Manager.
- Tools > Options > Advanced : Encryption: Certificates - View Certificates
Stored intermediate certificates show as "Software Security Device" in the "Security Device" column in the Certificate Manager.
thanks for your answer but the VeriSign certificate is correct:
SSL CERTIFICATE STATUS: Valid (Jan 14, 2009 to Mar 14, 2012)
I have this problem with Windows 7 and Windows Server 2008. Why is it working on win XP?
Check the date and time in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
thanks again, the time is correct in guest OS and server OS. I'm geting crazy!
Try to rename the file cert8.db to cert8.db.old in the Firefox Profile Folder to remove all intermediate certificates that Firefox has stored by visiting secure websites.
Help > Troubleshooting Information > Profile Directory: Open Containing Folder
I renamed the cert8.db but the problem is still there. It happens the same with Firefox 5. I think the problem is the verisign certificate of the site (other site's with https connections are working well) but I don't know where is this problem exactly.
