还是SSL问题，打扰大家了，火狐不支持，后来跟SSL供应商沟通，它说证书是没问题的，并提供了SSL证书测试，结果错误信息如下：
The certificate is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate. Learn more about this error. You can fix this by following Comodo's Certificate Installation Instructions for your server platform (use these instructions for InstantSSL). Pay attention to the parts about Intermediate certificates.

希望有经验的大神指导一下，鄙人不懂英文，但是我对互联网的知识却是无限的渴求，谢谢！
谢谢大家，目前已经搞定火狐浏览器不识别该证书的问题，方法如下

把根证书加入到你的证书内。
