See also the discussion in #DOM on cmo.

Basically, it seems like es6 modules don't get loaded in chrome:// xhtml files. See the attached example - chrome://pippki/content/test.xhtml only shows the alert from the non-module script, whereas chrome://pippki/content/test.html shows both.

See the comments. I'm not sure what the testing story is for the
prototype cache...

Not caching modules means of course rather bad performance. Hopefully modules won't be used anywhere in the main Firefox UI.
