CORS preventing reading contents of dat

[paul90]

Getting errors like:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at dat://ed8fd80fbbfb4396fdb1445f449563a52bcce1e3d10b48515a1ec784442dfb61/activity/factory.json. (Reason: CORS request not http).[Learn More]

when trying to read contents from a dat other than the origin.

This is when trying to run dat://federated-wiki-client.hashbase.io/ with dat-fox in the current developer edition of Firefox.

I notice later that the readdir calls are all returning a rejected promise with "Error: Another hypercore is stored here". A connected issue? deleting the problem archive from the datfox cache resolved the "Error: Another hypercore is stored here" error.
