I checked that page, and I don't see how to enable this natively. This page just seems to point people to install the add-on.

The anchor link doesn't scroll properly for me, but it's supposed to point to the heading "for advanced users".

The tl;dr is:

> you can set privacy.userContext.enabled to true and privacy.userContext.ui.enabled to true in about:config.
