They're probably only aware that Safari and Chrome display different things in the address bar. If they don't like Safari they'll switch to something they prefer.

Usually it'll follow a pattern like:

"Hey friend, my browser is a bit rubbish, I can't see the page I'm on."

Friend uses Chrome and demonstrates how it doesn't do that.

"My friend's browser is better because the URL is clearer. I'll swap to that one."

Non-technical users will usually follow recommendations like that before they considering looking for an option to make the browser work the way they want it to. Configuration isn't something most users do unless it's either suggested by the application or there's a button literally in front of them.
