"While we have performed extensive compatibility testing, it is possible that your website certificate will no longer validate with Firefox 31," the Mozilla Security Engineering Team said Thursday in a blog post. "This should not be a problem if you use a certificate issued by one of the CAs in Mozilla's CA Program, because they should already be issuing certificates according to Mozilla's CA Certificate Policy and the BRs [the CAB Baseline Requirements]."
Mozilla also created a special bug bounty program that will pay out $10,000 for any critical security flaw found and reported in the new library's code until the end of June.
"As we've all been painfully reminded recently (Heartbleed, #gotofail) correct code in TLS libraries is crucial in today's Internet and we want to make sure this code is rock solid before it ships to millions of Firefox users," Mozilla's security lead Daniel Veditz said Thursday in a blog post.
"We are primarily interested in bugs that allow the construction of certificate chains that are accepted as valid when they should be rejected, and bugs in the new code that lead to exploitable memory corruption," Veditz said. "Compatibility issues that cause Firefox to be unable to verify otherwise valid certificates will generally not be considered a security bug, but a bug that caused Firefox to accept forged signed OCSP [Online Certificate Status Protocol] responses would be."
