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.

12 weeks is the absolute minimum amount of time we need to make changes.

How can you test your pins?

1. 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.
