From https://www.torproject.org/projects/torbrowser/design/

Design Goal: SPDY and HTTP/2 connections MUST be isolated to the URL bar domain. Furthermore, all associated means that could be used for cross-domain user tracking (alt-svc headers come to mind) MUST adhere to this design principle as well.

Implementation status: SPDY and HTTP/2 are currently disabled by setting the Firefox preferences network.http.spdy.enabled, network.http.spdy.enabled.v2, network.http.spdy.enabled.v3, network.http.spdy.enabled.v3-1, network.http.spdy.enabled.http2, network.http.spdy.enabled.http2draft, network.http.altsvc.enabled, and network.http.altsvc.oe to false.

It looks like there's issues with HTTP/2 being able adhere to the URL-bar domain isolation that Tor Browser does.

  • How does it affect the privacy of the tor browser users? Can you please give me a brief explanation about the URL bar domain isolation? – Aswin Kumar Apr 9 '18 at 6:54
