They’re the ones who make the user.js who decides it. But it changes a lot of the settings so web pages can break.

user_pref("browser.search.region", "US");
user_pref("browser.search.geoip.url", "");
Will this keep me permanently in the US, whenever I go to a website? Does that website think I am looking at the website from US?

No. It makes it so Firefox won’t do a geolookup to see where you are located when providing search results.
