The version of Firefox I’m using at the time of publishing this post was Firefox ESR 45.3.0

ESR means Extended Support Release.

Why am I unable to find the option in “Preferences”? The answer I found on Mozilla forums is this:As a part of an effort to simplify the Firefox options and protect the users from unintentional damaging, Firefox has disabled Javascript and removed the option to enable it for normal users.
