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.

and
then why would you actually need to see the full URL? Come to that, why would _anyone_ who isn't debugging a REST API need to see the full URL?
This is the main problem with options over good defaults. An option requires enough understanding of the domain to realise that there might be other choices. It also requires enough knowledge to make that choice, especially for something that affects security (knowing if you're on a malicious website) but looks like a simple visual change (simplified URLs).
