Stability

Aurora

• Overall rate: 1.6 - browser: 0.8, content: 0.7 - yellow (target: 1.5)
• coming close to target, matching 46 now.
• Main concern is e10s-related crashes that the e10s team is working on

Beta

• Overall rate: 1.2 - yellow (target: 1.0)
• AsyncShutdown crashes are 2.3% of 46.b9 data, majority continues to be sanitize, see bug 1258350
• signatures are changing in bug 1189715 as expected, hopefully the new diagnostic data can help to find a fix. This is 1.2% of b9 crashes now.
• bug 1158189 HTTP shutdownhangs are 2.4%
• bug 1257387 GC tenuring OOMs are 2.4% as well

Comparing beta 8 and beta 9, stability looks about the same or even a bit worse in beta 9.

• https://crash-stats.mozilla.com/crashes-per-day/?p=Firefox&v=45.0.1&v=45.0.2&v=46.0b8&v=46.0b9&hang_type=any&os=Windows&os=Mac+OS+X&os=Linux&date_start=2016-04-01&date_end=2016-04-12&submit=Generate (compare days with similiar ADI, so for beta 8, look at 04/07 compared to beta 9 on 04/11. )
  • some of the crash fixes in beta 9 didn't really work or don't have a visible effect (bug 1259089, 1229252, 1259699)
    • The first and the last were never a large amount of beta crashes, so high impact on rates was not expected.
    • On the second one, the HTTP shutdownhangs are subject to a lot of speculation on potential fixes, this one one of them that didn't directly help

Release

• Overall rate: 1.00 - yellow (target: 0.95)
• bug 1258562 (fixed in 45.0.2) is 2.5% of 45.0.1 data
• Trusteer bug 1255026 on Mac (trf.dylib@0x1c3a7) is still unchanged
• noticeable spike in crashes for https://bugzilla.mozilla.org/show_bug.cgi?id=1264504 in 45.0.2
