Hello,

Thanks for your answer. I check with the Firefox latest version (eg 145.0.1) and it looks like HTTP/3 support is enabled by default.

Indeed, in the adress bar I submitted about:config and searched for network.http.http3. and found that network.http.http3.enable is set to true :-)

Best Regards.
