Is it possible to write a WebExtension in WebAssembly?

I wonder if it is possible to use WebAssembly to develop an add-on for Firefox.

I doubt that it is possible to do completely in WASM, but what about WASM core with minimal JavaScript wrapper?

I don't see why not. Why don't you try it? You could start from this tutorial: developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/… – Cheremkhovo 24/9, 2018 at 15:52

it would be interesting to do it with Kotlin. It can work as JS or as WebAssembly with the same Kotlin code. – Jam 19/10, 2018 at 13:48

Yes, there are already WebExtensions using wasm, e.g. see the release notes for uBlock Origin 1.17.4.
