when is last possible beta for a fix (Beta 9?)? or has that passed due to crash stability with earlier Beta being the higher priority?

Add-ons

Stability

Aurora

Overall rate 3.08 (browser 2.13, content 0.96) content crash rate has significantly dropped on aurora since mid last week \o/

Beta

Overall rate 1.15 (browser 0.95, content 0.20)

[philipp] 50.0b7:

• crash pattern with specific intel cpus https://bugzilla.mozilla.org/show_bug.cgi?id=1296630 (7.95% of browser crashes)
  • This is something we can use to tweak update rules on RC builds
• crashes with nvidia driver dlls https://bugzilla.mozilla.org/show_bug.cgi?id=1310600 (>3.9% of browser crashes)
• crash in std::list<T>::clear() from D2D1::EndDraw() https://bugzilla.mozilla.org/show_bug.cgi?id=1308863 (2.6% of browser crashes, 3% of content crashes)
  • possibly fixed by bug 1307749 in beta 8; otherwise there would be a pretty solid regression range for this signature in the bug report
    • bug 1307749 seems to just fix an assertion
• startup crash in chtbrkg.dll@0x... LSP module https://bugzilla.mozilla.org/show_bug.cgi?id=1290403 (1.85% of browser crashes)

• content crash in IPCError-browser | (msgtype=0xAE0005,name=PNecko::Msg_PHttpChannelConstructor which is marked as blocker went away in beta 6 & 7 without a specific patch landing for it: https://bugzilla.mozilla.org/show_bug.cgi?id=1289001

Release

Overall rate 0.92 (browser 0.74, content 0.17) Looking pretty good.

Nightly

[marcia]

• Explosive crash https://bugzilla.mozilla.org/show_bug.cgi?id=1310189 is now resolved fixed by a backout. This was the largest volume crash we have had in a while.
• https://bugzilla.mozilla.org/show_bug.cgi?id=1308603 has one signature that is still crashing. Marco filed a Socorro bug to get it added to the skiplist
• Project Uptime bugs filed: https://wiki.mozilla.org/Platform/Uptime/NightlyCrashTriage/2016Q4#2016-10-18_-_ting
• Filed https://bugzilla.mozilla.org/show_bug.cgi?id=1311064 - Crash in nsSupportsArray::Read
• More JS crashes than usual. Billm added new places where we paint while we suspend a JS GC, and then added some assertions in bug 1308039 that we don't do anything with JS while this is happening. That is causing some new JS signatures to surface.
  • Reference bug https://bugzilla.mozilla.org/show_bug.cgi?id=1279086

Mobile

• New Aurora crash filed: https://bugzilla.mozilla.org/show_bug.cgi?id=1311056
