  • Perf P2 bug 1174770 - tpaint regressions (3%-8%) in e10s mode compared to non-e10s mode
  • Perf P1 bug 1186585 - 19.66% - 44.84% tps talos regression with e10s enabled and APZ disabled
    • I'm reasonably certain the test is flawed in its measurement, and is favouring non-e10s. See my arguments in bug 1261152
    • Currently in the process of re-writing part of tps to be more accurate. Initial results look promising, hoping to have solid data from a try push tomorrow.
  • bug 1263887 - [e10s] The dropdown selector is not working properly.
    • We triaged this last Tuesday, and I was asked to do investigation. The problem is that script on the page is mutating the <select> dropdown after it has opened.
  • Fixed regression bug 1260461 - Firefox fails to exit on system shutdown
    • This has now been uplifted to aurora / beta. Waiting to hear back about ESR.
  • Fixed regression bug 1255773 - Page Info - Media is incomplete
