I was able to replicate the user-facing error, but the errors originally logged in the console are now resolved, but instead it seems to blow up inside of Firefox with `AbortError: Actor 'Conduits' destroyed before query 'RuntimeMessage' was resolved 2 ConduitsParent.sys.mjs:383 _raceResponses resource://gre/modules/ConduitsParent.sys.mjs:383`

This looks like you might be using concurrency in your JS for the import and a timeout is being hit?
