Firefox 31 Post-mortem

   Two last minute backouts this cycle

   New tab

   Last minute call to disable it

   The feature was not easy to disable

   Confusion from QA

   UX related backout (but if only I could find the bug #)

   Have added product/UX review to end of Nightly cycle to catch these issues earlier

   Update experiment

   25 % update for a day is working great

   will repeat the experiment a third time with 32 after which we may attempt to get more aggressive

    ESR seems on track

   We accepted a few stability/webcompat patches

   We accepted a number of fixes because we were kicking off a new ESR cycle for 31

   Perhaps we should be more vocal about the upcoming ESR (2 cycles in advance?) in future

   Web compatibility regression

   Bug 1043690 Verizon webmail gives a null 404 error because <input name="action"> shadows HTMLFormElement.action's setter

   I don't think we have much in the way of web compat regression testing - this is a known blind spot

   Some SSL/https issues related to the new mozilla::pkix

   CA cert issue on Fanfiction.net (maybe web-compat?)

   May need to follow up with Fanfiction.net's CA cert issuer to see if we're doing something different

   https://bugzilla.mozilla.org/show_bug.cgi?id=1046223 ?

   Probably caused by https://blog.mozilla.org/security/2014/04/24/exciting-updates-to-certificate-verification-in-gecko/

   Data entry failure in ship-it for build1 (wrong entries for previous version numbers for partials)

   Partial missing for RC1/RC2 => beta 1  (31 => 32)

   Should be fixed now

   confusion about what build to ship for FxAndroid Build 1 vs Build 2 to ship to the Play Store

   if it's very clearly only a desktop issue, only do a desktop build instead of respinning mobile as well
