* AddonSettings.EXPERIMENTS_ENABLED

* Experimental APIs are always available to privileged signed addons.
* This constant makes an optional preference available to enable experimental
* APIs for developement purposes.
*
* Two features are toggled with this preference:
*
* 1. The ability to load an extension that contains an experimental
* API but is not privileged.
* 2. The ability to load an unsigned extension that gains privilege
* if it is temporarily loaded (e.g. via about:debugging).
*
* MOZ_REQUIRE_SIGNING is set to zero in unbranded builds, we also
* ensure nightly, dev-ed and our test infrastructure have access to
* the preference.
*
* Official releases ignore this preference.
