Where can i find Firefox configuration page?

i want to learn to build Firefox extension.
in the very first parts of book it has been written:
“Go to the URL about:config to view the Firefox configuration page and enable
two options: javascript.options.strict and javascript.options.showIn-

actually i cant find this Firefox configuration page.
gratitude for your atention.

What book…?

So that’s saying in the URL bar, type this in “about:config”.

Cool, now at the search bar at the top of hte page, just type in “javascript” and all javascript options (including what you need) are there. Do as the instructions say.
