Is there a way to force FF to use HTTP/3? There are multiple instances (youtube, for example) when site says "alt-svc: h3", but FF ignores it and keeps using at best HTTP/2.

Hi

As a first step, I recommend updating your copy of Firefox as you appear to be using an older version.

Does this help fix the problem?

Enter about:config in the address bar and confirm that network.http.http3.enable = true.
