* The code for fixing URL bar input in Brave is written in JavaScript, see https://github.com/brave/browser-laptop/blob/master/js/lib/urlutil.js
* The equivalent code in Firefox is written in C++, see https://searchfox.org/mozilla-central/source/docshell/base/nsDefaultURIFixup.cpp
* The equivalent code in Chrome is also written in C++, see https://cs.chromium.org/chromium/src/components/url_formatter/url_fixer_unittesturl_fixer.cc and https://cs.chromium.org/chromium/src/components/url_formatter/url_fixer.h
Read through both files and try to orient yourself. Don't get hung-up on understanding every single line, especially in the Firefox code, which uses lots of internal APIs and [https://en.wikipedia.org/wiki/XPCOM XPCOM base code]. Instead, try to find clues as to how each one is doing what it does with input strings before converting them to URLs.
