Is it possible to develop Firefox browser extensions without writing JavaScript / TypeScript?

Hello, I was looking at WXT extension framework which supports multiple UI frameworks, but they are all JavaScript frameworks only. Is there any alternative way to write Firefox browser extension in a different language (like Rust / Python / Go, etc.) with minimal or no JavaScript , with a ok developer experience?

Transpilation to JavaScript is fine if it is well supported in Firefox with ok developer experience.

I also checked Dart but its support on Firefox does not seem great, like the extension only works on Chrome browsers.
