Unfortunately, the longer answer is that you're not going to match the
security offered by Tor Browser in this way.

Currently Tor Browser is a fork of Firefox, meaning there are 100+
patches applied to the code before it's built:
https://gitweb.torproject.org/tor-browser.git/log/?h=tor-browser-31.4.0esr-4.5-1&showmsg=1
and some of the patches close serious privacy vulnerabilities that
Mozilla for whatever reason hasn't chosen to address.

You can read more about Tor Browser's goals here:
https://www.torproject.org/projects/torbrowser/design/
and an old but still useful discussion of attacks to consider is here:
https://www.torproject.org/docs/torbutton/en/design/

So in conclusion, I would recommend against acting as though you've
made your arm Firefox thing 'close enough' to Tor Browser.
