I realize some things, especially related to Preferences might not work as expected. I don't know for ::Add*VarCache but ::GetCString() might always return the default value because user pref will not be read yet.

Patch v1

r=jst, but please do make sure that the preference values do get read correctly this early in startup (or that the value gets updated once the value is available).

Once you land this, the null-check you added to the DOM memory reporter can get backed out, right?

If there is no weird situations where about:memory is loaded after ::Shutdown(), yes.

Backed out because of build failures on inbound.

Are you seriously only calling Init in debug builds?

This broke DOMWINDOW printfs because you removed the --gRefCnt.
