The confvars.sh in XULrunner doesn't have JSGC_GENERATIONAL enabled. As a result, XULrunner doesn't have GGC enabled although the code has been there since v31.
I've filed a bug in bugzila (https://bugzilla.mozilla.org/show_bug.cgi?id=1063911) bug but haven't got any feedback so far. Can someone with the rights to submit patches help rectify this?
