Help, I need to change my pinset!
File a bug under the Core::Security:PSM component with changes to your pinset: https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=Security%3A%20PSM&short_desc=%28pinset%20change%20request%29
How much notice do I need to give for pinset changes?
Firefox is on a 6-week cycle, with 4 different trains: Nightly, Aurora, Beta, Release. For the next merge date, please see RapidRelease/Calendar. We prefer not to make changes once Firefox is in Beta, and the current lifetime of the pinset in Release is 8 weeks. Therefore we need at least 14 weeks notice for any pinset changes, preferably 20.
I have an emergency!
In emergency circumstances, we can release an emergency update to the stable channel to change your pinset in 24 hours. No one wants to do this. We will consider removing you from the pinning program altogether in this event.
How can you test your pins?
- Install desktop Firefox 32 or later.
- Go to about:config and make sure that security.cert_pinning.enforcement_level = 1 (allow user-specified trust anchors to override pinning checks) or 2 (strict mode). There is an additional enforcement level, 3, for enforcing test pins if you'd like to enable that instead. Normally test pins are used only for counting pin violations, but not actually enforcing them. You will have to coordinate with the pinning team in order to verify which of your pins are in test mode, and which are in production mode.
- Visit https://pinningtest.appspot.com to make sure you see a warning.
- Visit all your sites!
What platforms does this affect?
Official Firefox Desktop only. We may enable this for Fennec in a future release, once we learn best operational practices on Desktop. We don't have a plan for b2g right now.
