Rust initially started as a hobby project of a person who happened to be a Mozilla employee and later got sponsored by the foundation however it was not a language that was specifically designed with browsers in mind.

The language's largest project before it hit 1.0 was Servo. The language wasn't designed for browsers, but it certainly was informed by them and their struggles with maintaining and developing Firefox.

a lot of early rust design was driven by Servo - an internal mozilla project, and firefox component prototypes

How could browsers not be on his mind when his job was to contribute to Firefox as a dev?

Do your hobbies revolve around the benefits for your employer? I don't mean it in a snarky way either, but given that Rust was initially written in OCaml, you could see how it could go like "I like programming, I like type systems but I want something procedural over functional so let me give it a go".
