This new module simplifies how we interact with PerformanceInfo counters: - CollectPerformanceInfo: returns all PerformanceInfo instances - NotifyPerformanceInfo: converts PerformanceInfo in XPCOM and notify them MozReview-Commit-ID: JedKEtsbQTF --HG-- extra : rebase_source : c87ad34f116a789f909c480963fb99cae3fafa6d
