Previous Actions

Schedule Update

  • Best to push the schedule back for 46. beta->release merge, Apr 18 Merge: Apr 25 Release: Apr 26
    • We missed nearly 3 betas (with beta 1 only being for en-US). Beta 3, beta 6 skipped, beta 7 late (released yesterday)
    • Firefox 47 still planned to release on June 7.
  • The schedule allowed for a 7 week cycle between 46 and 47 release. Changing that to 6 weeks for 47.
  • This helps l10n as well for 46 (delayed by the infrastructure issues last week)
  • more time to iron out any issues with build promotion
  • more time to land crash fixes and react to beta 7/8 changes
  • Better crash data with e10s disabled (experiment cut-off didn't land till beta 8)
  • If we delay 46, we will do a 45.0.2 (probably tomorrow)
    • Discussed about cancelling it because only 2 weeks away from the release but as we are delaying 46 ...
    • A top crash
    • Some web compat issues
    • No single drivers but all combined...
    Bug 1254980 -       Copy-pasting selected HTML from Firefox to a new Thunderbird message (using TB 38) or to BlueGriffon is broken as of Firefox 45
    Bug 1257861 -       Firefox 45 fails to send Cookie header with XHR post requests done from a web worker when third-party cookies are blocked
    Bug 1260961 -       Legitimate CORS requests are blocked by Firefox 45.0.1
    Bug 1258562 -       Crash in dom::MediaSource::Duration - top crash
    Bug 1256442 -       Ship 1.1.x of the Loop system add-on to the release population
    Bug 1258650 -       Yahoo finance chart comparison "overlays" not displayed properly because of bad interaction with scaled clip and mask combo
    Bug 1259482 -       Product image not changing upon selection in Woocommerce/Wordpress




Overall rate: 2.5 - browser: 1.0, content: 1.5 - red

  • signatures of bug 1259699 are the top 3, fix uplifted yesterday


Overall rate: 1.3 - browser: 1.1, content: 0.2 - red. Not worse than beta 5, anyway (these numbers are still mostly about b5 and earlier)

  • Looks like e10s is still on for a significant amount of people, is there still an ongoing experiment? Yes, it turns off in beta 8
  • bug 1246108 (wasapi_stream_start) is fixed in b7
  • AsyncShutdown crashes are 1.9% of early b7 data
  • bug 1189715 (gfxContext::gfxContext, #6 top crash in b7, 1.4%) still happening in beta 8 although we though we had a fix in bug 1259810


Overall rate: 1.0 - yellow

  • Trusteer crash bug 1255026 definitely decreasing on Windows, but the OS X signature continues to be high #16 or so on release? How bad is bad?
  • Flash game crash bug 1252152 has decreased noticeably last week


Performance (Thu)

Aurora / Dev Edition





Aurora / Dev Edition


  • 1262149 - Firefox users with OS X 10.11 and QuickTime 7.7.3 cannot playback video content requiring this video player and are prompted to use Safari instead. (all branches - not just beta)
  • I noticed with OS X 10.11, each time I restart (or maybe reboot) I am prompted to make Safari my default browser now (or later) There is no option to say "never ask me again".
