DOM Storage is a pretty inefficient and memory-hungry storage mechanism. Session Store attempts to record DOM Storage for each tab, which leads to (possibly very large) objects being serialized once to be sent from frame/content to parent and once to be sent from the main thread to the I/O thread. This is a suspect behind a number of crashes (see bug 1106264 for a discussion on the topic).
This patch limits the amount of DOM Storage that Session Restore attempts to store. We perform a quick estimate on the amount of memory needed to serialize DOM Storage and prevent storage larger than ~10M chars being sent from frame/content to the parent. Once this patch has landed, we will need to watch FX_SESSION_RESTORE_DOM_STORAGE_SIZE_ESTIMATE_CHARS to find out whether our threshold is meaningful.
