Schedule Update

• We shipped 54 beta 1 last Friday. Delays for e10s multi issues to land.
• 54b2 should go out today (desktop is ready, fennec not signed off yet)

• Turned off updates for 53 desktop on Friday because of ESR update issue (now resolved) and maybe for the nahimic issue. Updates unthrottled back to 100% around noon on Monday.
  • Can we add a SUMO article and/or release note advising users of the workaround?

• We will need to ship Fennec 53.0.1 (build 2) GTB later today or tomorrow morning. Drivers are:
  • Bug 1355870 - Provide a way for distributions to set a custom path to customizations (not yet landed )
  • Bug 1354911 - Crash in java.lang.NullPointerException:
  • Bug 1356563 - Race condition on startup that can break opening of initial/restored tabs
  • Bug 1358131 - TalkBack broke with upgrade to 53.0
  • Bug 1354038 - [push-apk] taskgraph: Use 'rollout' and deactivate dry-run on release (so we can control staged rollout)

• • maybe ridealong, Bug 1358089 - [RTL] broken UI layout after last update

• 53 desktop status: No clear dot release driver. 3 ridealong candidates: 1356637 - nahimic block, 1358487 form validation, 1348409 window.find assertion

Roundtable

• screenshots status?

Does it block 54? Uplift and test in beta... will we have enough beta cycles to test? what about automated test coverage Test plan is important = the criteria needs to be updated for non-test pilot (not adequate for a Firefox feature). We need a risk analysis Peter de Haan is the official QA person for this What is the go/no-go date? Staged rollout is the plan (John Gruen has more details) 54: 6/13 (.1% of release on the 19th of June) Metrics to be monitored A few days later it will be shipped to 5% of the release

• https://bugzilla.mozilla.org/show_bug.cgi?id=1359495 <== we need to uplift this for beta 3

• question about overall volume of crash data reported for 53 fennec is significantly lower than 52 (40%) : https://www.arewestableyet.com/longtermgraph/index.html?andrel
  • some popular media related fennec crashes in 52.0 are drastically declining: https://bugzilla.mozilla.org/show_bug.cgi?id=1339496 & https://bugzilla.mozilla.org/show_bug.cgi?id=1341360

Special Topics

• https://bugzilla.mozilla.org/show_bug.cgi?id=1356637 Nahimic issue.
  • we can blocklist them completely, but that won't help users on 52 or 53 who still won't be able to update
  • blocklisting them will mean all MSI / nahimic users will have sound volume at 50%.
  • they plan to push a fix for the updater problem in mid-may, but we should still blocklist because it is a dll injection against our policy for 53 onwards.
  • user impact?
