Greetings, friends of Mozilla,

We are a Certification authority, but from Mozilla Firefox 37.0.1 we have been having troubles to access pages secured by our ssl web servers certificate. Customers receive the "sec_error_bad_der". we haven´t any troubles with Google Chrome or Mozilla Firefox <= 36 or even mobile browsers.

Our certificate is based on Openca (not Ms Active Directory trouble RSASSA-PSS) and have similar fields templates of others like Verisign. I have been reading https://support.mozilla.org/es/questions/1031483 post.

our certificate is PKCS#1 RSA key 2048 with SHA256

Another issue. if we access one of the webpage with trouble by ip address instead of the web address, its works ok...

do you need any aditional info?
