Add-ons

Stability

[marcia]

• Regarding https://bugzilla.mozilla.org/show_bug.cgi?id=1295033, we did get permission from a user that crashed in this signature and have shared it with our contacts at Kaspersky for investigation. This crash is present in 50.

Aurora

Beta

[philipp] a heads-up for everyone looking at beta stability numbers - infobar submission mechanism for unreported bugs also turned on on "early beta" https://bugzilla.mozilla.org/show_bug.cgi?id=1303067:

• rates will go up and are no longer be comparable to prior cycles or for all builds within the same cycle
• does not make sense to report socorro based crash rates for beta in this meeting anymore (only early betas? https://hg.mozilla.org/releases/mozilla-aurora/rev/b128f5deb5e4#l1.13 )
• some plugin crashes will get misclassified as browser crashes & startup crashes: https://bugzilla.mozilla.org/show_bug.cgi?id=1318136

51.0b1 early data

• websense is dominating the list of crashers:
  • mozilla::net::nsStandardURL::EqualsInternal https://bugzilla.mozilla.org/show_bug.cgi?id=1313085 (3.5% of non-infobar browser crashers)
  • qipcap.dll@0x5f1f (0.7%)
  • PREF_GetIntPref (0.3%)
• crashes in COIDTable::ThreadCleanup & DisconnectSwitch https://bugzilla.mozilla.org/show_bug.cgi?id=1294903 (3.9%)
  • was regressing in firefox 50, we backed out the underlying cause of the crash there
  • has a speculative patch in the bug

Release

Overall rate: 0.96 (browser 0.76, content 0.20)

[philipp] 50.0

• various crashes with malicious chtbrkg.dll LSP https://bugzilla.mozilla.org/show_bug.cgi?id=1290403 7.2% of browser crashes (declining, 5% in the last 24hours)
• crashes with IME regressing in 50:
  • InvalidArrayIndex_CRASH | nsTArray_Impl<T>::ElementAt | mozilla::widget::IMMHandler::HandleComposition && InvalidArrayIndex_CRASH | nsTArray_Impl<T>::ElementAt | mozilla::widget::IMMHandler::DispatchCompositionChangeEvent https://bugzilla.mozilla.org/show_bug.cgi?id=1300140 (3.5%) - Fixed in 51
  • InvalidArrayIndex_CRASH | mozilla::ContentCache::TextRectArray::GetUnionRectAsFarAsPossible https://bugzilla.mozilla.org/show_bug.cgi?id=1291082 (0.4%) - Fixed in 51
  • most comments by chinese users; seem to indicate firefox crashes reproducible while switching input method from english to chinese
• e10s crash in nsCOMArray_base::InsertObjectAt https://bugzilla.mozilla.org/show_bug.cgi?id=1318102 (9% of content crashes)
  • newly filed - needs triaging + investigation

Nightly

[marcia]
