I found that TCP Fast Open was removed in Firefox, while Chrome continues to have it. Does anyone have more info on why the devs decided to axe it ?
The ticket that removed the feature didn’t have any explanation: https://bugzilla.mozilla.org/show_bug.cgi?id=1689604
Protocol ossification is a huge problem. That’s one of the reasons why the IETF went with the UDP based QUIC for HTTP/3.
