If you don't want to run JS garbage collection before cycle collection, use nsIDOMWindowUtils.cycleCollect method: | |||
window.QueryInterface(Components.interfaces.nsIInterfaceRequestor). | |||
getInterface(Components.interfaces.nsIDOMWindowUtils). | |||
cycleCollect(Components.classes["@mozilla.org/cycle-collector-logger;1"] | |||
.createInstance(Components.interfaces.nsICycleCollectorListener)) | |||
A file cc-edges-NNNN.log will be created in Firefox's current working directory (usually the current working directory where Firefox was started). This file contains a dump of the heap known to the cycle collector, which includes JS objects and also native C++ objects that participate in cycle collection. | A file cc-edges-NNNN.log will be created in Firefox's current working directory (usually the current working directory where Firefox was started).
