I was thinking new stuff was done in Rust. I guess Gecko is CPP only?

I think some Rust components have been written and integrated into Firefox. But the core Firefox codebase - including Gecko - is still C++ so it's not easy use Rust there.

On a related note, Chrome is looking at integrating Rust into its C++ codebase.

Not true majority by far is done in c++. Easily confirmed by downloading the browser source and using a LOC analyzer to see how much code is done in which languages
