A use-after-free condition existed in NotifyOnHistoryReload where a
LoadingSessionHistoryEntry object was freed and a reference to that
object remained. This resulted in a potentially exploitable condition when
the reference to that object was later reused. This vulnerability affects
Firefox < 115.
