We create a wildcard certificate for our domain to use in local intranet (*.oudomain.com). It works perfectly with Google Chrome and IE, but not working in FF 33 and later. Is there any solutions?

thanks, mozilla's documentation for developers contains the following information for this error code:

What it means? A certificate with a basic constraints extension with cA:TRUE is being used as an end-entity certificate

What can I do? Re-generate the end-entity certificate without the basic constraints extension https://developer.mozilla.org/en-US/docs/Mozilla/Security/x509_Certificates#Error_Codes_in_Firefox_2
