I have patches for necko part of this bug. We should work on the dom part of the implementation in bug 1409290.

Change to httpd.js test server and a test for the 103 response.
Attached patch bug_1407355_v1.patch (deleted) — — Splinter Review
The change to nsHttpTransaction.
Propagate early hint response from parent to the child. I have implemented a new interface nsIEarlyHintObserver instead of extended nsIRequestObserver. It is possible to extend nsIRequestObserver as well, this only depends on how many observer we will really have and that depends on how we implement bug 1409290. Maybe we will need to propagate early hint responses through the listener chain(in that case we should extend the nsIRequestObserver interface).
Priority: P2 → P3

Any news on this?

I expect that website owners will only start to use early hints once a major browser supports it, but server-side support has been added in several servers/frameworks, for example:

nodejs also supports it

The upcoming release of lighttpd 1.4.56 supports 103 Early Hints

Some movement here on the chrome side, intent to prototype:

Dragana, not quite sure if the proposed use of 103 reponse for a chrome trial is a great idea. Any thoughts?

This is on my radar already. The document shows interesting possible performance improvement from the telemetry they have collected (it sounds also a bit high). There is not a good spec for this feature, e.g. integration with fetch spec is missing. In one of the docs they proposed 2 possible implementation, but I would prefer to have some spec or at lease a draft that we can discuss. Anne had similar comment.

I was thinking about adding telemetry to estimate possible performance improvement in Firefox (if you are interested to help :) ).

Is this picking up steam now here due to Cloudflare enabling beta Early Hints on accounts?

This is live in Cloudflare and out of beta, I just toggled it on for my website.
