Need To Know

(Release and system issues that may impact engineering this week.)

Notices/Schedule (lsblakk/sylvestre)

• Firefox Desktop & Android 30.0 is live
  • 25% of pop being offered updates for 24 hours (this is an experiment in uptake/reducing throttling time)
• Firefox ESR 24.6.0 live
• FF31 beta 1 will gtb within the next few hours
• Aurora updates are currently disabled, re-enabling on Friday once QA signs off
• Might need to disable OMTC for FF32 as it is responsible for 5 of the top crashers on that channel right now

Next Merge: November 10, 2025		Next Release: November 11, 2025
Trains
Central: 146	Aurora: 54	Beta: 145	Release: 144

Build Changes (gps)

(Build changes of which engineers should be aware.)

RelEng (catlee)

(Repo, test, and other information for engineers from the release engineering team.)

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

Quality Programs

(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)

OrangeFactor (ryanvm)

<Read Only>

• Past week's OrangeFactor: 9.66 (Previous Week: 8.05).
• No changes from last week: OSX 10.6 mochitest-4 continues to timeout and B2G continues to crash. More tests featured here previously disabled prior to the uplift.
  • bug 947531, bug 891840, etc.
• #4: bug 1014355 - Intermittent Linux "ABORT: X_FreePixmap: BadPixmap (invalid Pixmap parameter)" in nsX11ErrorHandler.cpp.
  • needinfo? Bas pending since 30-May (comments 38, 39, and 46).
• 26 intermittent failures fixed in the last week - List - Thanks!.
  • Thanks to Drew Willcoxon for fixing bug 870205, a frequent source of pain.

MemShrink (njn)

• I missed this last week: Emanuel Hoogeveen fixed a problem with our page allocator in the JS engine that can lead to virtual OOMs even when there's address space available. This may help significantly reduce the virtual OOM rate on Win32. Emanuel is working on a similar fix for jemalloc.

Team Stand-ups

(In <2 mins, what did your team accomplish last week, on what is your team working on this week, and on what, if anything, is your team blocked? No questions during the stand-ups. All questions should be asked during the roundtable.)

Developer Tools (robcee)

• bug 1016578 Inject script libraries into content via GCLI
• bug 1005909 Clickable Links in console output
• bug 907310 Reload key commands available in detached devtools toolbox
• bug 911209 Show hidden (display:none) nodes differently in inspector
• bug 718250 Show node dimensions in highlighter
• bug 1017790 Expose category information in Profiler data
