I am aware of the updated STIG v4r4 for Firefox. I will be updating the add-on as soon as possible.
Reference this tracking ticket: STIG V4 R4
Please post support requests at the Caffeine Security Secure Firefox Google Code page.
This add-on has been developed implementing the recommended about:config settings from Defense Information System Agency (DISA). The implemented settings are part of the Mozilla Firefox STIG - Version 4, Release 3, which is available from DISA at http://iase.disa.mil/stigs/index.html, or NIST at http://web.nvd.nist.gov/view/ncp/repository/checklistDetail?id=356
Please note this may cause compatibility issues with some websites. Should you encounter compatibility issues, simply disable the add-on until you are finished browsing the site.
Not all DISA STIG items may be enforced by this add-on. STIG items such as the installation of DoD certificates will not be included. This is intentional. Please use official DoD channels to obtain the DoD certificates.
