Good stuff. Would you consider adding extensions.install.requireBuiltInCerts, per https://bugzilla.mozilla.org/show_bug.cgi?id=688383 ? The message displayed in the Error Console is vague and doesn't explain how to work around the problem. Needed to install development builds of AdBlock Plus, among others.This review is for a previous version of the add-on (188.8.131.52-signed).
