@binarynoise, I am able to reproduce this with LANG=de_DE.UTF-8. Looks like it fails the testing process. I will update this comment with the issue I will be creating upstream. Thanks.
Edit: https://github.com/mozilla/web-ext/issues/3676
Edit 2: I have added a workaround to the PKGBUILD, by running npm test with LANG=C, until the issue is resolved upstream.

@sun_lmao I have updated the PKGBUILD to allow all versions of nodejs. However, Mozilla recommends using the LTS version, so if there are any problems in building in the future, also try using the LTS version.
