Firefox 81 Beta and Developer Edition are out, worker MIME type enforcement now in place

Mozilla shipped Firefox 81 Beta and Developer Edition today.

While other changes are relatively minor, take a moment to check out the six compatibility notes for the new release that will be out of beta in late September.
