• bug 1156742 - print to xps with low integrity sandbox - fonts are really hard - fixed various problems found in testing:
  • memory corruption from the way I was pulling out names from TrueType files
  • timeout due to misunderstanding the way nsPagePrintTimer works
  • added a load of null checking to the Moz2D event playback code, as it currently just expects everything to be fine
  • added a new patch to only send the font data once and cache on the parent, scaled font then reference that
  • just found issue with TrueType font collections for GDI fonts, working on fixing that now

• M8 bug 1209689 - Crashed tab indicates all tabs have crashed and every tab loads the crashed tab page
  • Waiting on last reviews.
  • This will make it so that if the content process crashes, the background tabs will be restore on demand, even if the user has restore on demand disabled. This is to avoid a crash loop in the event that the crash was caused by a background tab.
• M8 bug 1171708 - [e10s] Stop using CPOWs for window closing
  • Patches up.
• M8 bug 1177310 - [e10s] Stop using CPOWs on application shutdown
  • Starting on this. This is my last M8 (for now).
• bug 1193838 - Make it possible to gather profiles from processes that have exited, and bug 1103094 - Start profiling subprocesses if the parent process is already profiling
  • Haven't started on this yet - hoping too once I get my last M8 out the door.
• The usual reviews
• Gave JS / DOM onboarding. Also been doing lots of debiased interviewing duty.
