I have the same problem, seems to be related with the service worker not finding some chunks.

In my case the issue seems to have disappeared after I had to delete my local storage from my Firefox profile because of corruption. If I remember correctly, to do that you have to move/delete .mozilla/firefox/profiles/<something>/storage{,.sqlite}. Note: you may loose some data from some websites or extensions.
