Comment (by tom):

 Sorry to be a nag, but are you certain that this won't happen in the
 future under similar circumstances?

 To address pinned cert rollover, most browsers will not enforce pins N
 months after the build date of the browser.

 To address the 'several version update' FF does just that. We will tag
 watershed releases that all users must update through. So if you're on
 firefox 20 you may have to upgrade through (hypothetical example)  20 ->
 28 -> 35 -> 42 -> 50 -> 56.  Watersheds aren't planned, they just occur
 when they're necessary for things like mandatory SSE2 support, signing key
 rollover, etc.
