The OPFS is subject to browser quota restrictions.

  > The OPFS is subject to browser quota restrictions. FWIW, 256mb last i checked (summer 2022). Perhaps less on mobile browsers, but that's just speculation.

  Which means nothing unless the defaults are restrictive. What are the default browser quota restrictions on install?

    OPFS doesn't really change this concern that much. IndexedDB already allows for relatively arbitary blobs of data to be stored per site (subject to existing quotas)

      IndexedDB should also be disabled by default. Adding more and more storage options instead of restricting the existing ones that are already being abused is madness.

  So any sufficiently motivated/funded malicious actor who can register a whole bundle of domains can use up 50% of the entire free space on my disk? Am I getting this right? Is the only defense against this the requirement for per-origin permission to be granted?

    That's been true for over a decade. Hasn't happened in the wild though AFAIK. I don't think there's an incentive for anyone to do this.
