Evaluation

Sandboxing TCP/UDP socket in a separate process

Risk & Mitigation plan

Socket process isolation will be landed behind a pref, therefore:

  • Shield study will be employed on a proportion of Firefox users before to gather performance/stability data without affecting all users at once.
  • Go Faster add-on can be used to disable the feature on designated channel immediately when major regression happen after default on.
