In a fresh profile, it looks like we import 7 different .jsms in a content process: resource://gre/modules/ExtensionContent.jsm resource://gre/modules/ExtensionChild.jsm resource://gre/modules/ExtensionCommon.jsm resource://gre/modules/ExtensionUtils.jsm resource://gre/modules/MessageChannel.jsm resource://gre/modules/ExtensionManagement.jsm resource://gre/modules/Schemas.jsm With four content processes, and at about 30kb per .jsm compartment, that's around 840kb of memory. I looked through ExtensionContent.jsm, and it seems like it might not do anything useful if there are no extensions installed. It would be nice to avoid that overhead if we can, given that many users do not have extensions.
