I was attempting to install a web extension via about:debugging. In the extension manifest, I'd accidentally left in: "default_locale": "en", (I was going to add localisation later). When attempting to load it via about:debugging, all that Firefox told me was "There was an error during installation: Extension is invalid". I did some debugging, in xpinstall, there's a proper error raised, it just doesn't get raised to the UI. Please can it get raised up properly, it would help first time web extension developers a lot.
