47.0b8

• introducing a blacklist for crashy modules with d3d11 dxva media playback in 47.0b8 & it has worked well ( https://bugzilla.mozilla.org/show_bug.cgi?id=1273691 )
• crash in TppTimerpExecuteCallback with ati gpus https://bugzilla.mozilla.org/show_bug.cgi?id=1270686 (set to block firefox47) is down to 0.5%
  • the volume has decreased by half in beta 8, so it might be of less urgency now
  • this looks related to d3d11 dxva playback as well, since the crashes ceased on exactly those devices which were blacklisted in beta 8 \o/
• crash in nsPresArena::Allocate https://bugzilla.mozilla.org/show_bug.cgi?id=1275239 related to a fairly obscure 3rd party extension is at 0.7% (#3 on kairo's top score board though, due to happening repeatedly for some users)

notable crash fixes that are approved to go into beta 9:

• shutdownhang |... nsThread::Shutdown https://bugzilla.mozilla.org/show_bug.cgi?id=1258009 is at 1%
• _dwrite_draw_glyphs_to_gdi_surface_gdi https://bugzilla.mozilla.org/show_bug.cgi?id=726206 is at 0.45%

Release

Overall rate: 0.99 (orange) startup crashes: 0.13, shutdownhangs 0.20

• blocklisting trend micro's addon in https://bugzilla.mozilla.org/show_bug.cgi?id=1275245 is working and rates are declining (combined signatures were over 1% on 46.0.1 before - in today's data it is at 0.15%): https://crash-stats.mozilla.com/signature/?date=%3E2016-01-01&signature=wcscpy_s#graphs yay!
