I’ve become increasingly interested in Oblivious HTTP (OHTTP) and Oblivious DNS-over-HTTPS (ODoH) and I am wondering if there is a way to test this today with Firefox (or any other browser).
It appears some relevant options have been exposed in Firefox’s about:config settings:
I’m not positive but I believe that these settings are only for DNS over oHTTP (sometimes called: DoOH (“Dns over oblivious http”)), which I think is either a successor to or a renaming of ODoH, not a fully fledged implementation of OHTTP.
Does anyone know if there is a way to test Oblivious HTTP in the wild today (excluding Apple’s private relay if that counts)?
Bonus question, does anyone know of any ODoH compatible DNS providers apart from Cloudflare?
