1631446 - Safelist dat, dweb, ipfs, ipns, and ssb schemes for registerProtocolHandler()

Status: UNCONFIRMED

(Core :: DOM: Navigation, enhancement, P3)

Description

[Frédéric Wang (:fredw)]

These schemes were added to WebExtension's procol_handlers in bug 1428446.

After bug 1476035 we switched to a whitelist (as described by the spec) for registerProtocolHandler, so it's now inconsistent with WebExtension's procol_handlers.

This is currently being discussed in chromium / HTML5 there:

Could we make this encompass all the schemes that seem reasonable that have been requested?

Yes sure, it seems it's not clear which ones are "reasonable" for now. I'm just opening this for the record and will update the things when there is an agreement on the WHATWG side.

I would request we add the did: scheme to the list of entries here, given it is a standard track technology being specified in a formal W3C Working Group: https://bugzilla.mozilla.org/show_bug.cgi?id=1639016

IIUC:

• Chromium already includes ipfs://, ipns:// and other schemes on their safelist (https://www.chromestatus.com/feature/4776602869170176)
• Fédéric has patch for Firefox ready (https://phabricator.services.mozilla.com/D71580)
• The HTML spec is waiting for... not sure. Mozilla Position in https://github.com/mozilla/standards-positions/issues/339?

How can we unblock this?
