By the way, even though it is not yet turned on by default, http3 support is present in Firefox and can be activated by toggling 'network.http.http3.enabled' in about:config to true. I have had it enabled for a few weeks and everything seems okay except that rarely I've noticed a few sites not loading the first time I visit them but needing a 'refresh', but I'm not sure if this is because of the new QUIC code or just another connection glitch.
