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

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.

Ideally we'd like to have 18 weeks notice before any pinset changes, in order to have adequate time for testing and uplifting (if necessary) to Aurora. For the next merge date, please see RapidRelease/Calendar.

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)
  2. Visit https://pinningtest.appspot.com to make sure you see a warning.
  3. Visit all your sites!
