How can I implement a javascript whitelist without using add-ons?

more options

From the link below

http://kb.mozillazine.org/Allowing_only_certain_sites_to_use_JavaScript

We know that we can use Configurable Security Policies (CAPS) to implement a javascript whitelist. But after version 28, CAPS is removed from firefox. Therefore, we lost a built-in javascript whitelist feature.

Who knows some solutions or workarounds? ( Please note that DO NOT USE ANY ADD-ONS OR PLUGINS! )
