Mozilla says that the statement from their Director of Ecosystem Development regarding the "ten fucking days" for security updates isn't their policy:
This is the official Mozilla word: This is not our policy. We do not think security is a game, nor do we issue challenges or ultimatums. We are proud of our track record of quickly releasing critical security patches, often in days. We work hard to ship fixes as fast as possible because it keeps people safe. We hope these comments do not overshadow the tremendous efforts of the Mozilla community to keep the Internet secure.
