4 bugs to triage

  • 1307713 - Core :: General - Firefox operations degrade after reaching 2gb of RAM


    erahm, what do you think?

This one is a bit weird, I have another ni out to the reporter but we're seeing several thousand non-window zones and hundreds of top-level windows. They're on ESR 45 so honestly there's not much we can do code-wise but we can at least see if add-ons etc are contributing to their problems. I'd probably give it a P3.
  • 1309115 - Firefox :: Untriaged - eaten memory in seconds


This is ni? but seems pretty bad. I can attempt to repro on Windows.
  • 1311039 - Core :: Untriaged - about:memory gives a negative response in some areas


 It looks like we're failing to query heap-allocated for this user. Inclined to P3, but maybe it's a wider issue on OSX 10.12?
  • 1311422 - Firefox :: Developer Tools - about:debugging and service worker debugger leak compartments in nightly 52
